I used to do similar back when I went out to late night clubs. May be asleep till midnight or 1 then hit the doors an hour or two later, come in around sunup sleep till 10-11 am ( or maybe noon or 1). It's like an even split 24. I also used to have to go to 3-4 clubs in a night to collect for bands I booked, when I knew no use in being there till closing time. Did that for years.
