I agree with freeowl: what a terrific opportunity to start anew in a place that isn't framed, for you, by alcohol.
You'll probAbly find that there are plenty of people on your campus who do not drink. Different colleges tend to have different atmospheres in that regard (the small college where I teach is pretty academically oriented and not much of a party school). However, even at schools with party reputations there are plenty of folks who don't drink. It is about connecting with like-minded folks.
I'm so excited for you! What do you plan to study?
