Last couple day's of normal life

I am trying to enjoy my last couple day's of normal sleep wake cycle.  Sunday night I officially move to night shift-7 pm to 7am.  I don't know if I have blocked out how tired I was when I worked nights for a year or if it really wasn't that bad.  I think I am just trying to tell myself that.  Hopefully things will go smoothly.  I am really liking the Emergency room and feel like I am learning a lot.  I still sort of feel like I have just graduated again and am learning everything all over again.
