Petey,
Glad to hear that things are getting better. I had no doubt that you would find away to get rid of the tree debris. Compared to getting your treatment done, this was a snap.
You better get used to the weakness. Not from experience, but from what I've read, you will be in for some weaker moments. That said, the way you bounced back from the surgery, I wouldn't be surprised if you do well with the radiation, too.
Good luck.
Jerry
