Hello skeptical, welcome to the recovery forum. There is no instant cure. But he can stop. Whay you need to do is find a hospital where you live and talk your husband into the detox for three days. At the end of the three days he will be alcohol free. Now how he will remain so is another story. You could get in touch with the intervention people. I am told that they come to your home and intervene.

I am praying for you and your husband.
