I've always been the stereotypical fidgeter, of the obsessive pen-clicking, finger-tapping, leg-jiggling variety (I'm very fun to share an office with). I see a lot of people doing this and think it's a fairly common quirk.
But I have these other weird fidgets, too, and they've gotten worse recently. The first kind (leg-jiggling, etc.) I don't tend to realize I'm doing until the person sitting next to me tells me to cut it out. The other ones, though, are more like compulsions. They mostly involve flexing or stretching a muscle in a specific spot. It's like scratching an itch - if I resist, I feel a little crazy, and the more I think about them, the worse they get. It's to the point where I've become slightly self-conscious about my twitchiness, especially because I've had significant others ask me about it when we're falling asleep and I just have to explain to them that I'm weird.
I've wondered whether or not it's a Tourette's-like thing, especially because Tourette's is often comorbid with ADHD and OCD, and - surprise! - I have both. One thing I'm not clear on, though, is whether or not the Tourette's tics are "intentional," or whether they just happen on their own, like myoclonic jerks
(which I also get occasionally). I'm very conscious of these and can resist the urges, though I feel like AAARRRGGGHHH inside until I just give in. I don't really have any significant vocal tics, either, except when I remember something really mortifying.
I also think it sounds similar to Restless Leg Syndrome, but it definitely doesn't only happen in my legs. Or maybe RLS is a cousin of Tourette's?
Other things: The twitches began happening more frequently when I started taking Adderall for ADHD, which makes sense if they're related to a dopamine increase. I don't understand, though, why Tourette's would be related to ADHD if Tourette's is correlated with too much dopamine and ADHD is correlated with too little, and why the twitches and fidgets would get worse as the ADHD improved. Also, I've noticed that the compulsive twitches (and the myoclonic jerks, for that matter) get WAY worse on the rare occasions that I smoke marijuana, to the point that it kind of freaks me out.
Other possibly relevant information is that, along with the Adderall, I take Lexapro and Wellbutrin for depression, anxiety, and OCD. And hell, I may as well throw in that I had temporal lobe epilepsy as a kid. My brain is a big bag of endless thrills.
I also wasn't kidding when I said thinking about the twitches makes them worse - writing this question will have me popping and locking for the next two hours. AAARRRGGGHHH *twitch*
