Never smoked. I binged on alcohol in college, like most (maybe not most, but I'd say at least 40%, from how many people I'd see out on the weekends) kids. Granted, I didn't go crazy with it until I was in my senior year and 21, because I didn't want to get busted. I can't really say I got an addiction from it though, because now, just 2 years later, I haven't had a drop for.... well about three weeks now, but it's just something I don't think about. I never liked beer, because I drank to get buzzed and I'd get full from beer before I got a buzz going, so I grew up a vodka-kid haha.
I'm graduating to fine scotch and whiskey in a chilled glass now, though. Can't say I have any liquor in my freezer right now, but I've been meaning to pick up a bottle of Jack. Need to get to Tennessee and visit the factory, get some good stuff

As far as the drinking impacting my lifting... in college, I (like most kids) did isolation routines. I didn't get much progress because, firstly it was isolation routines, and secondly, my nutrition was horrible... and I missed a few workouts when I wouldn't feel like going from a hangover.
