Bibble probably not, no. But then many people will have a glass of wine or a beer on a night out to enjoy themselves; or when they get in from work to mark the end of the working day; or on a Saturday night to relax... drugs aren't consumed by society at large genereally in such a casual or accepted way. So it's not comparable anyway.
I agree that getting so drunk you don't know where the toilet is, or can't get up to look after your children, isn't great, but if he is enjoying a night out and she calls to chase him up, I can see the frustration. The "FFS, even on my night out I'm not free from it".
That doesn't mean she should suck it up. And I don't think anyone has suggested it. What most people have said is when you are calm and he is sober/not hungover, talk about it.
It really isn't any fun living with someone whose anxiety has to be managed down constantly and it can mean that when someone gets a break from it, occasionally they might think, "woohoo!" and go off the rails a little bit.
I'd be concerned if this were a regular thing. And I wouldn't be happy with the level of drunkeness, but just getting in at 3 once every couple of months or so a bit the worst for wear isn't really hurting anyone.
And as for the OP only having half an hour's sleep due to anxiety, that really is an issue for her to manage, not one for her husband to manage.
