Stop bragging you Canadian swine! I'm onto your devious plans. Canadians are trained from birth to undermine the U.S. monetary system by sneaking their dirty Canadian coins into our cash registers and vending machines. I think military intervention is required to stop it.

To the OP though, I could never work a night shift, I'm too prone to depression if I'm forced to sleep during the day. If you do any routine long enough your body will adjust, and so will your eating times. It's not odd that you don't feel good when you don't eat right. People take food for granted.. most people don't understand how much it can effect our bodies and minds. It's like a car, what you put into it you get out.. if you don't change the oil and use the wrong gasoline your engine will wear down quickly. I could have a biased opinion working at a pretentious organic market though. Honestly though, making healthy food choices can have profound effects on your energy levels and mental wellbeing.
