I just started back working midnights(00:00-08:00). We do 10 days on and 4 off which seems to work pretty good. In the past 5 years I probably have worked half of them on midnights. As far as sleeping goes, I am trying to hold out until 16:00 before trying to go to bed, although it isn't working out that way. Yesterday for example slept from 09:00 to 15:00, and then 21:30 to 22:30. It's just hard to get into a routine on this shift as there may be something you want to do during the day one day and then the next there is something you want to do on the evenings. If you have kids, it makes its harder also.
