Hi Becky,
Welcome! You've taken the first step by recognizing that you have a problem with alcohol. I'm Anna, alcoholic and I tried to cut down too and it never worked. But, you can stop, it can be done and we're here to support you. Just take small steps, don't let yourself be overwhelmed. And, I think a bonus of stopping drinking for me was that it was an emotional overhaul. I'm not the same person now and I'm glad of that!
As far as your husband not wanting you to stop drinking, that's difficult, but you will need to decide what you want to do for yourself. If you want to take care of yourself, then stopping drinking is the right thing. And, if your husband won't support you, you can find lots of support here.
Hang around and keep posting.
Love, Anna
