I usually have one glass or wine or one cosmo if I am out at happy hour. I don't have ANYTHING if I am driving because I am not sure how steady I would be with drugs and meds. I rarely drink at home, but then my mom was an alcoholic.
I take a LOT of meds, so for you, an occasional drink is fine.
Don't do the binge drinking in college...nothing good ever happens when you are drunk out of your mind.
