Hi,
Alcoholism is not about how much you drink or how often you drink.
Alcoholism is about what happens to you when you do drink.
It sounds like what happens to you is that you lose control. I can't tell you that you're an alcoholic, but to me, it sounds like alcoholism. Alcoholics cannot control their drinking. I think we have all tried doing that, not wanting to give up drinking completely, but found that things only get worse.
Take a look around and read and learn.
