It sounds like you have discovered you may have an issue with drinking before it has gotten too far out of control. That is good. Alcoholism is progressive, so if you are an alcoholic, it will keep getting worse. So what may seem reasonable/tolerable now may become uncontrollable if you keep doing what you are doing. Why not try and give up alcohol for 30 days or so? If you are concerned about it enough to post on here, you probably are on to something.
