Usually when someone asks this type of question it means you might be an alcoholic. I read the OP and it almost sounds like you are trying to justify your behavior, saying look alcohol is not a big deal in my life. But something very hard to do for an addict is be honest with yourself. I used to think my gambling was only hurting myself but then I realized how messed up it had made me. It takes time away from the addiction to see the truth.

So I'd suggest trying to stop drinking for a few weeks. If you can do it and it's not a big deal then you're fine. If you can't stop or you're always thinking about it, talk to a therapist or go to AA.
