How to enjoy alcohol again after a rough night

Hey! About 2 months ago I was out with my friends and threw up pretty bad after drinking Pink Whitney. Since then I have barely drank, and just the thought of drinking alcohol sometimes makes me feel nauseous. The few times I did drink after I threw up, I noticed I get bloated/stomach pain very easily which is something I did not experience before. I am going back to college soon and want to enjoy going out and drinking again. What can I do to help this?
