When I worked in A&E 20 odd years ago, one of the first things we were taught was "double the amount anyone admits to drinking". I don't think they'd have honestly had that unwritten rule if there wasn't a good reason for it. Occasionally the truth eventually slipped out one way or the other, confirming this to be reasonably accurate.
And now I'm married to an alcoholic. The reason he got away with it for so many years was: a) fooling himself about how many units he was honestly having, and b) because on his guilt-induced sabbatical he never experienced physical withdrawal like shaking. It used to be a real pita because he'd cut a day trip short to be home by 4 so he could start drinking. It's so much better now that he's stopped pumping his body full of a depressant toxin! He's got a better working memory, more motivation and sleeps better which obviously helps everything.
I'd say to anyone justifying their excessive drinking habits: please don't think just because you can stop for a few months that it shows you're not an alcoholic. They can all do that - it's talked about in all the AA shares and is part of the self-deceit!
The other thing from a medical perspective is that it might appear from your medical check-up's that you're managing to get away with it but the body works very hard to compensate for a long long time. The damage is an undercurrent ticking away that you don't see. So please be careful kinder to your body!
And now to answer the post. I drink socially but don't get out much because I've got 2 preschoolers.
I occasionally buy those tiny single bottles and give myself a glass at home, but only when my DH is out, which is kind of ironic because now I'm the one hiding my sneaky 2 units of red wine a fortnight!
