Me either. My dad drinks, but he's not a heavy drinker (more like a wine and beer snob), and he's a heavy guy (he's got like 100+ pounds on my weight, so it takes forever for him to actually get plastered).
I'm a devout nondrinker. Understanding my personality type as mood-less/depressive/secretive, I figure it's a bad idea. Without the inhibitions I normally have, I'd probably (1) have very wild mood swings and do anything from beating random people up to crying at the slightest thing since alot of my personality is held back just by being aware of what ppl might think, (2) the secretive part would probably go out the window and I'll tell everyone that I'm a crossdresser, into Taoist/Shinto nature magic, or generally weird ppl out with geekdom (in other words, alot like here), or (3) the depressive part might make me go ahead with suiciding myself if I was drunk and had a bad enough day (heck if I decided to have a drink, it probably is a bad enough day, since I don't do toasts either). The latter one is especially why I never drink, even if it might loosen me up.
