I have noticed over the last week that my sensitivity to caffeine seems to have dramatically increased. Normally, drinking coffee would have no major effects except making me slightly more awake / alert you would expect. But over the last fortnight, it seems that even drinking even a single cup of coffee has become quite unpleasant. 45 minutes later i will feel dramatically over-energised and find concentration difficult and drinking a cup of coffee after dinner at 7.30 will leave me unable to get to sleep until 1:30 or 2am. Is this a health issue? Is it likely that my body will adapt back over time (I do like the taste of coffee and would like to keep drinking it if possible) or should I switch to decaf coffee or a lower caffeinated drink like tea?

My coffee press screen has what looks like mold stains on it. (I left some tea in it for too long.) Is it OK to use? If I must remove the stains...how?

My brother-in-law used to run a coffee shop. He sold mugs with the slogan, "Coffee makes you GO!", alluding of course to that common side effect of coffee, diarrhea. My question is: 1. Why does coffee cause diarrhea? 2. What can be done about it, apart from (a) giving up coffee, or (b) taking a daily dose of Imodium / Loperamide? Coffee is like physics: we love it, and yet we hate it. Please help me hate it less. Bottoms up!
