Please don't think that you have to explain or justify drinking to me, I just used it for different reasons. And come on how can you not start early when your house has a room with a bar in it? :)
I never did the normal college thing, although I did graduate with a degree and honors. And think I need one maybe two more classes for a certificate in a different subject matter than my degree. But when?
But again each person's vice is their own. Then if it makes you feel better I can't say how much or not you should have, it's your decision, you know...you have to do what you feel is right to you. :)
