I don't know if you are an alcoholic or not Warren. Only you can answer that. If you are, it is not a question of morality. You don't seem to be an immoral person that doesn't know the difference between right and wrong or true and false. Alcoholism isn't about right or wrong, but does it work?
Having said that, perhaps you are not alcoholic. Try leaving your beer alone for a while and see how that goes. You've already answered the question about controling drinking when you are drinking. Try controlling it when you're not drinking.
