Quesiton about caffeine, energy, anxiety
October 7, 2024 12:49 PM

I have never had the relationship with caffeine most people have. I envy the relationship with caffeine most people have. Is this a thing I could learn?

I am typing this with unusual speed! I had TWO ICED TEAS and feel sort of like the meme of the woman with equations floating around her head. This is because caffeine in a small dose doesn't do anything in particular but at some secret point that is actually also a relatively small dose, I instead become jittery verging on hypomanic.

I think it's possible I interpret having much energy at all as a sign that something's wrong!

A guy I know told me yesterday that he used to have debilitating anxiety and then learned to treat that energy as "fear energy" and use it to get things done.

Do you suppose one can learn to stop experiencing somatic (oh, what to call this...) stimulation as a fight or flight response? IF SO, HOW? (Alright, those caps were just for comic effect.)

How do you do with warm, milky teas and coffees? I can drink two cappuccinos in a row and feel blissfully calm, but one iced tea and I'm getting heart palps.

Cold milky caffeine is energizing (iced coffee), cold cold black caffeine makes me jittery (iced tea), and sweetened iced tea hurry someone get the defibrillator.

So I'm a bit unclear what your question actually is....are you looking for the ability to have coffee, or are you looking for the ability to tolerate caffeine? Those are two different things.

* If you're looking for the ability to have coffee beverages - you may just do better with decaf. Shops are better about having decaf options now, and that may be something to investigate. Some of my friends just plain don't do well with caffeine and they've accepted that that's just how they're wired.

* If you are looking for the ability to tolerate caffeine....so, this is anecdotal, but it's something that one of those friends above recently discovered. They had similar anxiety and squirrelly thoughts when they had caffeine; so they avoided it for years. Then they started looking into their overall mental health - first exploring the possibility they had ADHD. Then they found that what they actually had was PTSD. They started seeing a therapist for the PTSD and have been making great strides in their overall mental health. But as a side effect - they've also been able to tolerate caffeine now, and in fact they've become an all-out coffee snob.

Disclaimer that I am absolutely not saying that everyone who has a problem with caffeine has undiagnosed PTSD. But if you have some issues with anxiety in general, there's a slim chance that addressing that could also tone things down to the point that caffeine is something you're okay with. Maybe.

I feel this; I really do.

I second phunnlemee; how do you do with hot caffeinated drinks? One thing I find is that with hot drinks? I tend to sip them slowly. But iced drinks? I gulp down. So, I can have two caffeinated drinks with the exact same amount of caffeine, and get wildly different effects, depending on what temperature I drink them at.

Do you have arrhythmia? Caffeine can do anxiety-like things to people with certain kinds of heart timing/conduction problems.

Combining caffeine with protein and fat will help reduce the jitters and soften the crash. The supplement L-Tyrosine helps with this as well.

Two iced teas is (depending on the tea) actually a fair bit of caffeine. I consume maybe 150-200mg of caffeine every day and even for me, more than half a coffee all at once is potentially hazardous and can make me (physically) jittery and trigger all kinds of similar undesired "stimulant" side effects.

Caffeine is a powerful, highly dose-dependent, highly addictive stimulant. Just because it is legal and highly available doesn't mean it doesn't need to be treated with the same level of respect as amphetamines -- it can generate many of the same side effects and downsides. The difference between 50mg and 75mg can be extremely palpable; that's not something wrong with you, that's just the nature of the drug. Most likely, a lot of people who don't get jittery are people who have tremendous tolerance from large amounts of caffeine use.

I'm also a little unclear on the question - but I've found yerba mate to provide a similar boost as coffee/black tea but without jitters - an experience many people have. So you could try that instead.

I find even high-caffeine green teas (gyokuro, matcha, etc) give me a nice positive boost, but coffee makes me feel jittery and awful in fairly small amounts.

Obviously specific to my own body, but my doc said this is likely because the tea has L-theanine in it which moderates the affect of the caffeine.

The question in its purest form is "I HAVE ELECTRICITY IN MY VEINS AND AM GOING TO TYPE SOMETHING." Secondarily, though, it is about whether I can tolerate caffeine better or even learn to get from it what everyone else gets from it. I do drink decaf all the time because coffee is delicious. But then once in a while I end up dosing on caffeine and yipes.

If you take it every day then very soon you won’t be so sensitive to single dose effects. Also there’s a ton of variation among products.

It’s not a habit I would start in your shoes. I am crazy sensitive to caffeine but so addicted now that I have to taper my withdrawals not because of the headaches or fatigue but because of the insanity emotional crash that takes me weeks to get over. So I’d have avoided becoming tolerant of and dependent upon it to begin with. Enjoy the ENERGY and then go back to regular minute consumption.

Like, if I have a half my usually dose of coffee by accident (like I drink work coffee which is weaker) then I am weeping and depressed and it’s just… it’s astounding. And then once I have some more coffee like boom it’s gone, what was my problem again?

And yes when I started drinking coffee I would have anxiety attacks.
But also ALL THE ENERGY.

That’s how they hook you !

Your body can really be a barometer for just how much caffeine it is a fine line between wheee and overdose.

I can’t say whether this is universal but after about 20 years of trying to make caffeine work for me instead of against me, I quit, went through a shitty withdrawal, and now feel massively less anxious on a daily basis. I get less anxiety from prescription stimulants than I do from caffeine! So at least my anecdotal experience is that no, you can’t make it work for you. Caffeine has a negative effect on some people.

I would dose down and see how that affects you. Most baristas will make you a 50% caffeinated espresso drink if you order a half caff latte or the like.

I think you have your answer right there. Decaf works for you, more than that does not.

Now, you could do as others have suggested and go through more trial-and-error, like getting into the light/dark roast debate, drinking it black vs. with cream, try other forms like tea, etc. But it's really about what you want to get out of it. And maybe a little about the habit of having it, and deducing whether it's the ritual of drinking something caffeinated, or the actual caffeine.

Your larger question about "why does having energy feel wrong" is, I think, a separate thing. The caffeine might give you that energy, but in this case is just the vehicle, not the main issue.

I think this is just a brain chemistry thing you're going to have to accept. I know people who really can't do caffeine at all, like not even decaf coffee; I, on the other hand, find caffeine really calming and have essentially never had a bad reaction to it (unless you count the taste of all the burnt Pike's Place roast I drank in college, bleh). There's a running joke in ADHD circles that goes like "Everyone says amphetamines are so addictive, why do I keep forgetting to take mine?", which I think goes to show that people's brains just do react differently to different substances.

I had to give up caffeine completely for chunks of time for medical reasons. I am very sensitive to caffeine (when I was younger a Frappuccino would make me feel totally wired, shaky, and like my heart was going to explode). I started drinking a little bit of drip coffee with a ton of milk and sugar to help me get started during my re-introduction. Over time I started noticing less jittery effects and started to adjust the ratio in the morning to be more coffee to milk. After a few weeks I drink a normal cup of coffee or a latte with no issues.

Like most drugs, you can build a tolerance to caffeine. If you really want to build up some appreciation it might be best to use a caffeine source that is consistent- either something you make yourself or getting the same beverage at the same place around the same time of day for a while.

TL;DR : screw all those people getting high on indiscriminate caffeine consumption. You do you.

I too "envy the relationship with caffeine most people have". Deeply. Soooo muuuuuch ennnnvyyyyy. I've tried to be them, so many times, so many places, on four different continents. For the better part of the last three decades I haven't been able to use caffeine in the morning. Yes, that's right. And why yes it does fucking suck. The way my body reacts to it in the morning is terrible and completely different from if I have taken it in the afternoon, and -- key distinction -- after I've had a couple meals. I must eat before caffeine. Not one big breakfast then caffeine. But it must be a breakfast, then a lunch, and then the sun must be descending from its daily apex, and then and only then can I have caffeine without it being a shitshow. As for why this is ... I only have speculations based on armchair research, some of which (around blood sugar and insulin sensitivity) have been heard and discounted by at 2 endocrinologists. One of my theories is that because caffeine spikes cortisol and adrenaline, and my body has since a very young age been finely attuned to the action and influence of cortisol and adrenaline, so perhaps I am particularly sensitive to the ways caffeine triggers a spike in one or both of these. Also, my brain was installed with the Bipolar2 form of wiring, and since I saw hypomanic in your post, I had to mention this.

Historically I've had a less than 50% chance of somewhat-kinda-sorta-successfully benefiting from an occasional small dose in the morning, but given the long history of the likelihood of it not working out (and the cost to the rest of the day of it not working out), I hardly even try anymore. So instead I focus on keeping my afternoon dose low enough so that enough time has passed by the time I've gone to bed that I'm well past the 4-8hrs half-life of caffeine getting through my system, so that it doesn't affect my sleep. Because, eventually, after many years of poor sleep for a variety of reasons, enough good nights of sleep has led to me not needing the caffeine hit in the morning. Wanting, absolutely... who wants to use an uncaffeinated brain if one can use a caffeinated brain? oh, that's right, I forgot. The morningtime instance of my caffeinated brain is a complete a-hole who among other things reliably makes me feel like a horse has kicked me in the chest (and yes my heart is fine, cardiologist says so)

But I am way better off after having accepted and embraced the way my damn body appears wired to work, AND ALSO, for the preservation of my sanity and livelihood, I still have that caffeine (green tea or matcha) every early afternoon. In moderation. Except when I am weak and fall prey to the lure of espresso, which makes me lie to myself and my loved ones about what is good and real and gives me magical powers but inevitably leads me back to the dungeon of despair from which I must again climb.

Also, you can have TWO ICED TEAS from Vendor A that won't hit you the same way as TWO ICED TEAS from Vendor B. There is a ridiculously wide variety in the amount of caffeine available in drinks depending on source, preparation, other factors. There's a wide range of caffeine content between light roasts (more) and dark roasts (less). Black Tea Type A can have way more than Black Tea Type B, or Green Tea, or White Tea. How many bags tea bags were used in the brewing of your energizing Iced Teas?

I've had luck with using high-quality matcha powder at home. I can control exactly the amount used in the drink and I believe it provides a relatively consistent level of caffeine day in and day out. Speculative of course.

Last comment on this topic which I have obviously spent WAY too much of my shortening life's time contemplating : I have read varying opinions on whether caffeine is a diuretic. I have read that people who drink coffee and tea and soda all day are going OK in terms of meeting hydration needs. My experience is has not been that at all. If I'm not hydrated already before having caffeine, it will not be a great experience, even the relatively reliably non-crappy Afternoon Caffeine Experience.

Good luck on your exploration into finding whatever works best FOR YOU !

p.s. building on the insightful comment above from molasses808 : decaf has caffeine. depending on your body's level of caffeine sensitivity, decaf can have a non-trivial amount of caffeine. more info

Is it possible it's the sugar in the iced tea that's doing you in, rather than the caffeine? I drink quite a lot coffee and tea with only milk or cream - no sugar - and it's totally fine, I could easily drink a gallon of either. But if I have a sweetened hot or iced or slushy coffee thing from a chain restaurant, or any other sugary drink, I feel wretched from the sugar crash.

p.p.s there is a reference in a comment above about L-tyrosine. I have heard many many mentions of L-theanine, instead, as the companion known by some to modulate the effects of caffeine. Green tea contains L-theanine, but you can easily find L-theanine over the counter or over the Amazon.

I react very differently to different sources of caffeine, so perhaps you can shop around for something that suits you. For me:

Oolong teas, most black teas (both British/French and Chinese "red teas") - a nice soothing beverage with a slightly gentle pick-me up

Sencha - much more "I am focused and energetic because I am drinking tea" feeling, and if I drink more than about 16 oz in under 2-3 hours I can feel wired and jittery.

Matcha lattes - nicely warm slight upper, I get full from the milk before I get any edge from caffeine.

Thai Tea from that one very specific coffee shop you know who you are - totally wired after drinking half a glass and also makes me run for the bathroom. So tasty, but really a terrible idea. (Thai tea from everywhere else seems to be... fine.)

Coffee - I never drink coffee. I accidentally ordered a black sesame latte last week (I thought it was just black sesame in milk or maybe a tea latte or I don't really know what I was thinking), and after 3 sips concluded that it was an incredibly tasty beverage that I needed to dump that drink in the trash IMMEDIATELY because I already was starting to feel jittery. I will return to the shop and try their tea another day.

If you just want something warm and cozy to sip and hold in your hands, try barley, ginger, or mint tea (all decaf). I keep them around for when I'm sick and want to drink something warm all day or don't want to overdo it on caffeine.

Different people respond differently to caffeine, because of brain chemistry and genetics.

People with ADHD, for example, often find that caffeine makes them sleepy. I can't find the article now, but apparently if you've got a particular gene, then you process caffeine more slowly than other people, with the result that you don't feel the effects till about an hour after drinking it, and then those effects last much longer than usual.

You can probably habituate yourself to a certain extent, by drinking it often, but there's a limit to how much that will affect the way your brain and body processes caffeine.

To your actual question, yes, it is possible to reframe the physiological symptoms of anxiety as excitement, but within limits.
Your nervous system can be above your window of tolerance because you're ecstatic or terrified, and the feeling in your body is the same.

Some people who have anxiety dislike exercise because they associate the increased heart rate with an anxiety attack, and it's often possible for them to reframe that experience over time.

But I think that works because you genuinely learn that exercise-heartrate is directly related to exercise-exertion, and that it's in your control.

I don't think you can retrain yourself to think that caffeine-anxiety is actually happiness-excitement, and even if you did, you'll still crash just as hard after.
