Per month, maybe two or three times I'll have 16-30 units of alcohol at a setting. I wouldn't bother consuming the calories if I'm not going to at least have 12 drinks or so. So, 30-50 drinks per month, I guess is accurate.
ETA yes, I drink alone. That way I never get in fights with anyone except the voices in my head
For reference, a fifth of whiskey has about 17 drinks, a 5 liter box of wine has about 34 drinks, and a 24 oz can of 10.6% beer has about four drinks. Those are pretty much the only things I'll buy. I also make wine pretty often -- but it's disgusting, like you'd be better off drinking mouthwash or cologne, probably.
I like it well enough -- nice change of pace (I don't really have any hobbies that don't feel like hard mental work to me). I usually just watch a few movies, maybe write some dialogue in a notebook, listen to some rock and roll, or in the summer months, if some shitty neighbors are having a loud conversation I can hear and disapprove of, yell out the window "I'm going to rape you to death with a knife, you fat pig, watch your back." That one's true. Nothing came of that, except neighbors don't generally fuck with me except maybe a very reserved "Hi!" Another good one, a few years ago, I was up at my condo's clubhouse using the wifi and some asshole started fucking with me, I think trying to goad me into taking a swing at him as an excuse to brawl. Apparently I said "I'm going to break your dick off and shove it up your girlfriend's ass." That one got a nice interview with the county sheriff, but nothing happened to me. Also, been taken to the town drunk tank, nerve damage from the handcuffs that was annoying. No charges, no record from that one.
So, yeah, without continuing that list of amusing anecdotes, you're damned right I drink alone. I'm not a mean drunk -- I'm an asshole sober as a judge -- just wildly unpredictable, so I just sit in my chair at home and take a little mental vacation now and then.
However, I find that while I never get hangovers, there are some brain damage-like effects that persist a few days afterwards, although I feel I've repaired the more serious brain damage from the years I was drinking much more heavily.
Not part of a balanced diet, but, eh, that's my answer to the OP.
