I might be wrong, but I think you're asking if it's not only possible to get and stay sober without AA, but without a program of sorts. History shows that it is possible. In fact it says in the Big Book, AA's basic text, in bills story I believe, that a doctor said in the early days that many had managed to get sober on their own, but an alcoholic of his type (bill) had never showed those results.
I suppose you have to admit to yourself what you truly are, in are you an alcoholic of the hopeless variety, or are you a problem drinker? At that point, depending on what you find, either look for help or exercise willpower to the point you have never had before. Also, around that point that I referred to it says something along the lines of a spiritual experience expelling the compulsion to drink, which is what AA is based around.
Hope this helps,
