For GERD you should stay away from alcohol altogether. It can loosen the LES and make reflux worse.
But there's nothing stopping you from going out in the evening. I'd avoid bars because the smoke can worsen GERD, but there are still plenty of things you can drink there, or preferably in restaurants. I have no problem with tea, although I generally carry my own teabags to be sure of getting a variety I like. I prefer green teas and especially decaf tea. Decaf coffee in small amounts is ok for some, but it does have a fair amount of caffein.
I actually like mineral water. I prefer the kind without the carbonation, but you can swirl it around and wait a while and a lot of that will dissipate. I keep an
open bottle handy at home because I don't especially like the taste of plain water.
Some fruit drinks are ok, but avoid lemonade, not only because of the acid, but it's loaded with sulfite.
