Hi. I know your situation well. My wife thought it was good that I didn't want to drink anymore but she still would say, "I still don't understand why you can't just have a couple." So I blamed it on the doctor to start, it made it easier. Everybody knows I have high blood pressure. Drinking and HBP are a bad combo so I said I was stopping until I could bring it under control. I don't think this is the safest way to go because you haven't truly let someone know, but it is better than nothing. Later on I told everyone that same story every time they asked me why I wasn't drinking. It may be a good call for you. Say you are allergic, whatever, just let everybody know that you are stopping as social judgement is a huge barrier to overcome.
