I mean, you aren’t trying to survive for the sake of survival itself, right?
What do you do for recreation? To decompress or just to get your mind off the everyday struggle? Board games? Perhaps you’ve figured out a way to watch movies or listen to music? Is getting drunk or high too much of a risk?
Some would eat pudding. :P
Alcohol isn’t going anywhere even in a post-apocalyptic world (whether people home brew or scavenge for old cans/bottles) but I’d guess people only really drink it in a secure setting behind walls.
For some communities if it’s safe-ish with some sort of walls/boundaries they’ll likely want to start gardening/planting things, that itself can be relaxing.
