I have to disagree, beli. It is not just an obsession. For an alcoholic, or any kind of addiction, there is actually something different happening in the brain chemistry having to do with the pleasure/pain principle and serotonin levels. I have actually studied this a great deal in dealing with a close friend with serious, life-threatening, addictions. I have no addictions on either side of my family as far back as anyone can trace. I can have, say, 3 drinks of straight liquor and feel nothing more than warmth and relaxation. More than that and I start to get drunk. This friend, however, has ONE drink and he begins slurring his words and absolutely cannot say no to another drink, and in fact he is then driven by something beyond his control to have another drink. It is a disease, not an obsession, although probably an argument can be made that obsessions might be diseases as well.
bsp77, it is really good that you are able to have such willpower and I think it is also very courageous of you to even question whether you might be an alcoholic.
