For a very long time, I thought I couldn't drink alcohol because I had diabetes. Of course, in college I did begin to indulge in adult beverages anyway but I always felt guilty because I thought I was doing something I shouldn't. Luckily, my endo later discussed diabetes and alcohol with me and I learned I could enjoy a cocktail.
ADA has a good resource on Diabetes and Alcohol. It's the kind of thing I wish I had when I turned 21. Check it out here: http://www.diabetes.org/food-and-fitness/food/what-can-i-eat/making-healthy-food-choices/alcohol.html
