I think a lot of us would agree that we would like to be able to drink once a week and be happy with that.
I gave up on that idea a while ago when I realised that it took about a week for my moderated drinking to turn into 1/2 bottles a night, and that was if I was lucky.
It is easier to not drink at all. When I first stopped, I would find myself salivating if I was around wine. That's gone now, but I know that even with over 2 months under my belt, it'll only take one drink to slip down that slope again.
