Your experience is very common. As the Big Book describes it:
At a certain point in the drinking of every alcoholic, he passes into a state where the most powerful desire to stop drinking is of absolutely no avail. This tragic situation has already arrived in practically every case long before it is suspected. The fact is that most alcoholics, for reasons yet obscure, have lost the power of choice in drink. Our so-called will power becomes practically nonexistent. We are unable, at certain times, to bring into our consciousness with sufficient force the memory of the suffering and humiliation of even a week or a month ago. We are without defense against the first drink.
And yet:
There is a solution. Almost none of us liked the self-searching, the leveling of our pride, the confession of shortcomings which the process requires for its successful consummation. But we saw that it really worked in others, and we had come to believe in the hopelessness and futility of life as we had been living it. When, therefore, we were approached by those in whom the problem had been solved, there was nothing left for us but to pick up the simple kit of spiritual tools laid at our feet.
I have come to conclude that there is a type of alcoholic whose only hope is Alcoholics Anonymous -- and I am one of those alcoholics. PM me if you want to chat more about that.
