Brdobu, I don't think that accomplishments have much bearing upon whether or not you have a problem drinking. Have you ever heard of high-functioning alcoholics? I drank excessively and smoked weed all through college, grad school, and in the early years of my career as a professor and artist. I was drunk at several university functions before I quit. Thankfully, that was so many years ago that few people remember the drinking me.
I meant to also say - I often wonder what I more I could have done if I hadn't been drunk/stoned while doing it.
