Hi op, I haven't read the entire thread, so just responding to your initial thing, I used to drink pretty much every night, got into some really bad habits late last year, wine wasn't my thing, just bottles of beer, but not massive ones! I was probably having around a pint a night, 2 pints if I would pop out to the pub, which I was probably doing around five times a week. Same as you, stressful day, and working really hard, so I really was framing it at the treat, I also work from home generally, so getting out in the evening to the pub to do some passive socialising was helping my mental health, I guess!
Really trying to rein in this year, and have managed really well last week and this week, down to just having 2 pints in a pub twice a week, Saturday and Sunday. And if I do have a bottle of beer at home, it's rare, they are 270 mil, I think, so around a half pint if not slightly less when I say a bottle, but it was the habit that I was really trying to break. It's hard though... Going out to the pub, or having a drink was helping to shape my evening.
