I was never a heavy consumer of alcohol, I never thought it was necessary to drink to have fun while in undergrad, but then again I wasn't a hardcore partier. The few times where I went nuts I ended up doing something I regretted.

At 22 I already feel like an old man, I enjoy the occasional glass of wine at dinner or formal events, and when I go out I just nurse a single beer for the entire night. My colleagues in law school though seem to drink a lot, and many of the people in the profession are alcoholics too.
