Does alcohol change your personality or bring out the real you?

I've noticed that some people act *very* differently while intoxicated, but I don't seem to (several people have commented about this). I tend to be very even-keel & in control of myself at all times. This would seem to lend weight to the position that it brings out the real you (doesn't change you) given that I don't seem to behave differently. Ideas/thoughts?
