When you are switching to the late night shift, you also need to think about your eating habits. The body must adapt accordingly. I usually awake in the mid afternoon and eat a big lunch. Then I will work for a bit and have a late dinner. Overnight I try to eat some healthy snacks and finally I eat breakfast as I finish my shift (just before I go to bed). Unless you are working in Las Vegas, then you need to remember that you will find it difficult to find food at 3:30 a.m. I will usually shop during an afternoon for some healthy snacks to keep at the console for the overnight munchies. Of course I must have some chocolate with me too, no matter what time of day I am working!
