Maybe "you" can't make yourself stop. Maybe you are powerless over alcohol?
I found a lot of success in conceding that could not make myself stop, I could not think the drink through, I could not "just say no", I could wake up in the morning and swear it off... but it was of little consequence, it was not my choice to make. I had lost the ability to make that choice long ago.
I found a lot of relief in conceding this, and accepting help in AA from someone who had been where I was, had suffered the same powerlessness I had, but had somehow found power to no longer drink, no longer even think about drinking-not even in passing.
