It's been well over 25 years for me, been there, done that, although it took a while, it didn't take too long to find out that it was not for me. I don't miss it, in fact I loathe it. The title asks about enjoying the nightlife, I really never did enjoy it. I went with the gang I worked with after work when we all were living out of town for work and had a generous expense account.
If I miss anything, it'd be the food. Thanks to the expense account I had some of the finest cuisine around in some really great restaurants in those days, but even with that I would never willingly walk back into that whole scene. Whenever I think back on those days I am reminded of the old song: "Is that all there is?"
