I felt the same way when I began college — unsure how to handle social drinking situations, especially having grown up around adults who didn't use alcohol in a healthy manner.

First off, don't feel guilty for having an occasional drink from time to time. It's normal, and there's nothing bad about drinking in moderation. Also, think about the drinking behavior of your friends — it can be hard for children of alcoholics to adjust to social situations that contain healthy drinking habits, since we're often used to being around unhealthy habits. It may be more difficult for you to go to social events where everyone just "gets drunk" — if you feel uncomfortable, it's OK to stay home or leave early.

My advice to you would be to think hard about your own personality traits and ability to moderate your behavior. There is nothing wrong with having a social drink. If you don't think you can handle just having a few drinks, then consider abstaining. I abstained from drinking completely all through college, and never had serious social problems doing so. (Plus, you save a lot of money!)

It also can't hurt to visit your school's Psych services if you want someone to talk to about this issue. Good luck! Your ongoing concern about this issue tells me that everything will be fine for you in the long run.
