I'm going to offer a different idea here and say, I would be fine with it. But within reason.
Maybe tell your husband to choose a drinking establishment that is close to home. To not exceed two beers/one spirit, so that he is still in a capable mind if you need him. Give him a time frame.
I understand why you wouldn't want him going yes, but I think with some reasonable rules in place, then I don't see a problem.
