I have never understood the point - or the reason - of going out late at night and staying up as long as possible.
When I drank, I got started early and usually finished relatively early. I finished early because I was either passed out or almost passed out. I'm talking about by 11pm or so. Sometimes I could make it til around midnight.
One reason I loved living in England was because the pubs closed at 11pm. Perfect. For me. Go home at 11 and get a decent night's sleep before starting work at 6am. But even when I was not working (for 5 years) I kept that same schedule. It worked for me as I'm a morning person anyway.
I bring this up because of this post by Joe.My.God. He tells of being invited to perform at a club but then everything shutting down shortly after midnight because everyone was too tired or too loaded to watch a performance.
It's not just my age because I have always been this way. But today, age has a lot to do with it. Even at our AA Center, I go home by 11pm. Ready for bed. Of course, I'm always by myself and don't have to compromise with anyone else on this.
