When I came back to Europe I tried drinking a few times, but I didn't really like it. As I hadn't been drinking, even one beer would make me feel so bad and dehydrated the next day (certain non-alcoholic beers do the same, so I don't think it is necessarily the alcohol). My wife was in the same situation, and then got pregnant so she also wasn't drinking. In the end I drifted away from my old friends who I would drink with, and made new friends who were happy to do things other than drinking.
Admittedly it does make certain social situations a bit awkward (my co-working space has a weekly beer night, although I'm usually not the only one who doesn't drink), but overall I don't miss drinking. Looking back the only reason I drank before was due to peer pressure; I never felt having a cold beer after work was a very effective relaxation technique.
