I can't sleep???

Dude, I can't sleep right now!  What is going on?  I feel great right now.  I actually feel alert and not so sore.  What is going on??????????????  I feel like I want to go run some errands, clean up the house and do some crafty stuff.  It's almost midnight.  What's the deal?  This is funny!  I am cracking myself up right now.  I feel giddy that I feel good!  I am such a NERD! What the heck???  :)
