That specific question (where does one beer fit in your Steps?) is in direct context of nutty's 1 step program. He claims that all he has to do is follow one step, which is to not drink. He also claims that one beer is not a relapse.
Correct and correct. For some people, this works.
There is in fact a support group with this goal in mind (Moderation Management). The "steps" of moderation management are more cognitive behavioral based and are not "all or nothing" or spiritual based. For this reason, MM has proven to be quite controversial.
(MM also, IMHO incorrectly, views that alcoholism is entirely behavioral, with no medical basis. IMHO, the correct answer is we do not understand enough about the brain to thoroughly treat alcohol addiction...)
I think MM is a more correct support group for quite a number of problem drinkers. I think there are certainly people, alcoholics, that should not follow a MM type program at all. (And some people may not even want a support group at all -- say, introverted types, right?) One has to determine whether or not they are an alcoholic (in which full abstention probably is necessary) or a problem drinker (in which case behavior modification may indeed work much better).
I'm not sure that AA treats addiction as a character defect, though, as wouldn't this imply that the solution for addicts is to behave morally rather than submitting to authority? I mean, I'm no expert on 12-step programs. . .
I'm taking the original 12 step wording from Wikipedia (see below). As far as I know, the main changes in AA have been to transform "God" into "higher power" from what I know...
3. Made a decision to turn our will and our lives over to the care of God as we understood Him.
4. Made a searching and fearless moral inventory of ourselves.
5. Admitted to God, to ourselves, and to another human being the exact nature of our wrongs.
6. Were entirely ready to have God remove all these defects of character.
7. Humbly asked Him to remove our shortcomings.
So yes, as far as I can tell, AA *is* a "behave morally" type of support group. The "higher power" is merely a framework and reason for changing your behavior. And if you are into religion / spirituality / higher order things of some sort and like to use that to help your behavior, that's great. But I do believe that the crux of alcoholism is medical. Which is why AA can only be used to control the symptoms, not cure (as they admit pretty much in the 12 steps).
