You cannot drink. Even one. Sorry. If you cannot do that get help in either AA or another treatment program. There are lots of them. Tell your husband you cannot drink at all. You dont have the ability to control yourself once you have even one. So head it off at the pass and dont have even a sip. As Nancy Reagan said: "Just Say No". Your husband will just have to drink by himself while you have a diet coke or something with twist of line and an umbrella in it!
