3rd shift workers what r u schedules like

So I started a new job last sunday working at a manufacturing plant n my schedule is Sunday thru Thursday 11Pm-7:30am. I eat dinner around 6-8pm n usually have a snack around 10pm. i get 2 breaks one 15 mins 5 1:30am n lunch at 4:30am. So 1st break I usually eat like a special k protein/fiber bar n for lunch i was eating stuff like leftover spaghetti or something heavy so i change it a couple of days ago n started takin homemade biscuits w/jelly n by the time i get home 7:50am im starving so my question what do u eat n how do u incorporate exercise into ur schedule? can u give examples of ur routine for night shift? I go to bed around 8:30am-9am then awake by 12-1pm n take a nap around 3/4-6pm if i still tired . I know I need to be gettin 8 hrs of sleep but its hard wit a 5 mo teething baby boy.
