Does coffee contain any other psychoactive constituents than caffeine? [more inside]
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!
