mikah, I'm just curious - do you avoid caffeine as well, or is the occasional soda okay? Do you actually have
coffee at the coffe meetings?

In college (of course) I did the pot thing only a handful of times, and I seemed to have to really work at it to feel anything other than thirsty. At most, I got slighlty giddy. It didn't seem to be worth the effort, although I never tried a bong.
LSD one time. Once.
Never did anything else other than have a few beers.
Now, I rarely even have a beer or a glass of wine, and when I do, I very, very rarely get excessive. We're talking a maximum of two or three drinks and I'm done. Let's just not talk about last New Year's Eve though...
