Tales of a night shift worker

During my orientation at Children's I was working day shift.  Having been working nights for over a year, I had no idea how lovely my body would feel back in the normal light of day.  No more nausea, crankiness gone, sleeping a normal amount of hours each week . . . it was lovely!  That being said, I am now back to night shift.  Just three days in and all the memories of a night shift worker are back.  I mean it's healthy to stay up for almost 24 hours straight every other week right?
