After over 25 years of working all over the place with management consultants on large projects I take sleep whenever I can get it.
At one point I was working 8am-4am for 6 months (before I walked out), but 12-16 hour days were the norm - usually with a 4am Monday start to get a flight, and a 4pm Friday return.
Weekends became the time to try to catch up on some sleep.
Now I never seem to want to go to bed, but no matter how early I do go to bed I never want to get up before about 10am.
Still get the occasional night where I'll wake up and feel completely alert, then look at the clock and go straight back to sleep.
