Anyone else gradually stopped drinking alcohol?

I stopped drinking alcohol some years ago. Before that I hardly consumed any alcohol at all for many years, but in my college years and maybe some years after that, I drank socially like "everybody else". But I gradually kind of got tired of dealing with the bad feelings (physical and emotional), so I drank less and less.

And maybe because I drank less and less, even one beer often just made me feel kind of bad, so then I just stopped altogether. Anyway, I'm curious if this has happened to anyone else? And how do you go by it socially? What do you order at a bar? Maybe I'm a little afraid to go to places that has an "alcohol culture", even if there are some places I would like to go. I don't want to drink, but at the same time I don't want to appear weird about it either.
