I used to drink a lot at the end of high school and begining of college. Not very often. Couple times a month, but when I did... well,I'll just say that I know from experience that "blind drunk" is not just a figure of speech. I had a lot of fun and don't regret it one bit.
For a while, I stopped almost totally, mostly because I didn't feel like it anymore and had no social life. Now, I have some beers once or twice a week. I'm always open to having a Guiness. Usually I have a couple at practice and before shows, as I play better when relaxed a bit. I had to stand in for our singer last show, my first time singing in front of people, and actually got pretty drunk. A bit of stage fright, even though there were like 20 people there.
