text: I feel for you, although I do not work nights my mom is a nurse that works the exact shift you do.  She has trouble with sleep and working it around a semi-normal excercise and eating schedule.  But she does it just like you would do it the other way, she eats several small meals at night and doesn't eat during the day, she sleeps then.  Gets up before work has dinner (or breakfast I guess to her) then excercises (or vice versa) and gets ready for work.  She does it the exact way she would do it if she worked the day shift.
