I'm one of those who CAN'T drink. But I think you're very smart because I used to be like you--for most of my life, in fact. Some of us do take a while to hit that point where we lose the choice about drinking.
FWIW, each time you navigate situations without drinking, it becomes easier. I always LOVED getting good and drunk at rock concerts. The first few I went to sober felt decidedly WEIRD. Now, I rock out with my diet coke and dance to the music and get into it the same way I used to back when I would be loaded. Not only that, I can remember details. LOL, I now make it a point to see bands I saw back in my college days whose concerts I know I went to but have no memory of. Just saw Fleetwood Mac again last year.
I occasionally think it would be nice to be able to enjoy a drink, but I would no sooner drink alcohol than I would drain cleaner, at this point. Not worth it.
