The fact that you don't get hangovers is part of the problem. If you did, you wouldn't be able to drink and function the next day.
Did you ever get hangovers?
I like drinking from time to time, but the hangovers put me off, which is nature's way of saying, leave off.
If I have more than four drinks I have to spend the next day in bed. I simply can't function.
I know a couple of alcoholics and neither suffer from hangovers (or ever have done).
When I read "functional alcoholic" I think of someone who doesn't suffer from hangovers.
I'm the same way. Four drinks is too much for me. I usually feel I the next day after 2. I.enjoy drinking for the duration of the act, and every moment after that is mostly regret.
You could also ask, what if time is the primary thing that exists? That is, it has authority over everything else that exists. This would mean that the laws of physics, for example, could change over time.
Similar introvert here. Open plan offices destroy me. It's a balancing act, not being too isolated so you get depressed, but having your own space really matters
In Brazil, architects often build a social space into their apartments. It's a good idea and works really well, but the people have to want to socialise together in the first place.
