I've never worked a graveyard shift but I have worked the late shift. This was when I was on a film crew several years ago. The shooting schedule goes for 10-12 hours which means the support crew works 12-14 hours and because of union/guild rules regarding turnaround time, the schedule gradually rotated around the clock during the week. One week I would start at 7:00 and eventually switched to starting work in the afternoon.

It screwed up my internal clock big-time. After a while though it almost felt normal to head out from the office to the set at 1:00am. The only way I could feel normal was to sleep as much as possible during my off time to offset the time differential. I guess it was like working constantly in different time zones. After the last movie, I basically said NO MORE and went back to my regular job in construction.

The upside was that I sometimes managed to get 9 or even 18 holes of golf in before I went to work! <img src="/images/graemlins/cool.gif" alt="" />
