I agree with you jazzfish (and Dr. Silkworth). I don't believe in an "alcoholic personality". I have seen too many varied personality traits in alcoholics to subscribe to that idea. However, I do believe that the incidence of psychological disorders is greater among alcoholics than in the general population. Depression and anxiety disorders seem to be overrepresented because people with these problems often find temporary relief with alcohol (only to then have their problem eventually escalate because of alcohol use).
I do see one common thread with most alcoholics, and that is on a spiritual (not a religious) dimension. Given the rules of this forum I'll just leave it at that.
