Re: Anyone work(ed) night shift?
If you really want to adjust well the most important thing is to keep your same schedule on your days off of work. Another thing I find to be key to feeling good on overnights and sleeping well in the day is exercise.
If you're healthy and somewhat young you should be able to at least partially adjust within the first week and should totally adjust (if you keep the same schedule every day) within 3-5 weeks.
It's really not so bad, I work overnights now and I have a 9 week old baby that I take care of during the day while my wife's at work so 3 days out of my week I only get 3 hours of sleep.
