As a college sophomore who has seen my potential dwindle away from too many beers id say cut it out as much as you can. I probably could be doing great things, but instead im stuck with my old prs, and a dorm room filled with empty beers cans. once you make drinking a regular habit, you find that all the guys you hang with are the same way and there isn't much of an escape from it.
Poor you. Don't be such a loser and start standing up for yourself. Don't want to drink as much? Don't! Your friends are all loser alcoholics? Get new friends!
