Aww sorry you're still feeling crappy.  Sucks you're in on the late shift too, man that can't be fun.  Get a nap in before you go, it might make it more bareable.
Sounds like you had a smashing weekend though!  Great North Run, wish I'd been there!  Wish I had the money to spend on being there, stupidly over priced!  Still, bet it was exciting to see though!
