> If OP wanted to write about how to fully participate in nightlife (2am outings, etc.) without drinking at all
In my experience, nightlife is even more fun with certain powdery and pill-y substances than it is with alcohol. Annoyingly they also negate the alcohol (but not the alcohol hangover), so you might as well not drink when you're using those. Waste of money and the hangover is going to be bad enough anyway.
I wouldn't suggest that kind of night out more often than every few months though. Whereas you can safely have an alcohol night out several times a month.
That said, as my workouts became more strenuous, my drinking has declined and almost completely stopped. I still drink alcohol on some occasions, but it affects my performance too much to be done regularly. And I don't have time to deal with the hangovers of other drugs, throwing an entire day away for a few hours of fun is not worth it [anymore].
And never forget: "People say you don't need to drink to have fun ... well you don't need running shoes to run, but it fucken helps".
