Yes Matt is right, Marie you need to be sober. BUT that doesn't mean you have to tell your husband the whole picture.
What's that name that Harry Potter's magician friends use to refer to humans with no magical powers---- MUGGLES?
Think of the normal drinkers around you-- those who would be freaked out by knowing the full extent of your problem- as MUGGLES. They don't get it. And you don't have to explain it to them fully.
Just give your husband the minimum necessary to help you with the logistics for awhile. Frankly, you could even give HIM the doctor/medication/ health recommendation line if necessary. Just get him to get rid of the booze in the house, and give you some space if you bail on a social engagement. You can bring him on board later with a full spilling of all the beans-- or you can say "Honey, these last 30 days have been so great, I'm going to make it permanent. Please help me out a little now and then. Trust me to let you know what I need."
