Dang this is funny! You all sound like you're ANCIENT!
I tuned my "partying" to the demands of the job I held sometimes I held two.
Because I was in a band till 26, my evenings didn't start till 9 and "work" ended around midnight on week days and apx 1:00 on weekends. That's when the party started...every night except Sunday and Monday. Then, I had to play catch-up with my non musician friends.
I put it all away when I had my first child-well, actually when I decided to get pregnant for obvious reasons. When your very existence means the world to another, you cut the risk and try and live to see another day. .....still, I have had my moments!
