I actually didn't drink at all until I was 21. I had 6 semesters as a member before I drank. Assuming your chapter has a house, spend a lot of time there, like week nights, studying and taking breaks to get a snack in the kitchen or watch a little tv. Get to know as many of your sisters as possible. Assuming you are already academically driven, you're probably going to continue to get good grades, and maybe your habits will rub off on your sisters.

I lived in the house for three years, and one thing I realized was that although some people go out 3-4+ nights per week, someone is always staying in to study on any given weeknight. Just try not to alienate. Emphasize your non-judgemental attitude by going out with your sisters on the weekends and not drinking yourself.
