I see that biologically unhealthy thing a bit. I just recently started a new job working in a Semiconductor Fab, which I go in 6p to 6a, 3 days one week and 4 the other week. And my body is still really confused, on when I should sleep and not sleep, and when to eat and not. The worst of it is the days I don't work and want to enjoy a normal day like everyone else but my body wants to sleep during the day and wake up at night. But the pay and benefits were great so it was good trade off I guess. But for ToddW at least its temporary for you, and hopefully you have a good transition during that period.
