I think the title should be "what I learned no longer participating in nightlife."
I can't think of anyone who participates in nightlife successfully who doesn't at least get a little buzzed when out. If you want to skip nightlife altogether, which is what OP seems to be advocating (going to sleep early, saving money), then of course, it's an easy choice not to drink.
If OP wanted to write about how to fully participate in nightlife (2am outings, etc.) without drinking at all, that would be more radical, and a pretty interesting read at that.
