Am I really an alcoholic if I am happiest when I am drunk?

I am drinking. Feels good. It's expected, the liquor is designed to do this to me.

But I dont wanna be sober now. I'm too damn happy. I feel like giving to charity and telling someone intimate details about me, things i seldom do while sober because i consider them to be symbols of weakness.

I work 7 days a week. Im enrolled for university this spring at one of the best damn schools in my country. Is it really a problem if I feel better drunk than sober?

I guess what im really askin is, when is someone an alcoholic?
