Hope you get the call soon Jim. When I first read your post and you wrote that you declined the pain meds my first thought was you should have accepted them even if you were not going to take them.
That's what I have done in the past and have a supply of "just in case" stuff there. Makes me feel better just knowing it is there if needed.
Sounds like I am preaching doesn't it wink Don't mean to..I guess it is just one of those hindsight is wonderful moments!
