Lots of good input above, but I am wondering, have you tried to cut back before? If so, how did that work for you last time, and why do you think it will turn out differently this time? Sometimes we ask questions when we already kinda know the answers, maybe in the hopes that someone will tell us what we want to hear. I have no idea if this rings any bells in this case.
For me, like many of us, I could not cut back for any length of time before I patted myself on the back and got good and drunk, again. It was just a cycle, until I gave up trying and just drank to avoid continuing to disappoint myself. Tapering was out of the question, if I could taper than I could have cut back early and not gotten so deeply stuck in the hole in the first place.
The only solution was a decision point, this is really it, I've already had my last drink and it's over, now.
