Petey,
Unless maybe there is a doctor reading this, I doubt the rest of us can make much sense of this, but I'm assuming that you know a lot more about what the drill is going to be by today--of course if you're really in the hospital for days, you won't be able to tell us!
If it turns out they didn't keep you overnight for 5 days, I'm hoping you'll be able to drop a short note and let us know how you're doing.
If even that is too much for you (I still remember feeling I couldn't read words on a computer screen, let alone type something coherent, when I was taking compazine for the chemo-nausea), know that many people here are thinking of you!
Nelie
