I'm 21, I've never really been a big drinker even now that I can do it legally. I don't ever feel like I have a need to drink or anything like that, I don't even consider myself a regular drinker to be honest. Whenever I do drink though, I have a problem of not stopping when I should, instead of just having a couple drinks, I'll want to continue to drink until I'm drunk. I honestly don't know why, and like I said I don't even drink often, maybe once a month if even that much. This has gotten me in some pretty embarrassing (sp?) situations a couple times, so what should I do?
