I was always more of a weed guy in my 20s, but I could tell I had alcoholic potential even back then. When I didn't have weed I'd always drink solely to get drunk, and I'd drink alone without blinking. I must have known there was trouble ahead cause I quit in 1993 and rarely even thought about it for years.
What I blame myself for is starting back up in 2001 when I should have known better. It's not like I was trying to drink socially or moderate either; I was looking for the pleasure of being drunk, pure and simple. Talk about hubris.
