Nurse on A night Shift

This morning, I went to the bank and the guy who served me was the guy who opened my account when I arrived here in Oz. He asked me how I was and if I settle OK with my work. I said yes and I told him I just finished my night shift this morning. His answer was a big "Yuck!". Yes being a nurse is difficult especially to never ending change of schedule. I just did 2 nights, I'm off today but I am back again tomorrow for a night shift. Then after a day off or my sleeping day I'm back again on day shift. And I think I will be doing this for the next 10 - 20 years... I hope not.
