You may be right about the AMA - I don't know.
Personally, I find it very useful to treat it as an illness and, perhaps paradoxically, I find that that allows me to take MORE, not LESS, responsibility - getting drunk is not something that "just happens" (because i never set out to get drunk, yet always did, and couldn't work out why) - instead, I now feel I have a clear set of symptoms, and precursors of symptoms, that it is my responsibility to manage, just like a diabetic.
Also, illness or not, it has a long history of requiring the intervention of doctors, for physical and mental health - this was well established by the time Alcoholics Anonymous ("The Big Book") was written and Jung himself features in it as someone who tried to treat alcoholism.
"It is simple. Don't drink, and if you do, don't get drunk." If it really was that "simple" - I am talking about reality now, rather than theory - then none of us would start threads like this.
