Party Plans-- What to Do?

Hi Ladies! First off, I would like to thank all of you for sharing your experiences. I've been reading all day long, and all of the tips and stories have helped put so many of my fears at ease.   Anyways, I am 21 years old, having my surgery on 7/19/12, currently a 36 DDD and hoping to be a full C. About a week and a half after my surgery, a good friend of mine is celebrating their 21st birthday. If I am healed by this time, would it be reasonable for me to have a drink or two with my friends? I don't intend on getting drunk or anything, but I want to know if this is a bad idea, as I have seen anywhere from 5 days to 3-4 weeks as time to stay away from alcohol. Any stories or suggestions would be greatly appreciated!
