They're on their way to Orlando for a chemo booster shot. He's going to have to get them on day 7 and day 14 of the chemotherapy cycle. Right now he's sleeping. Brian and Sissy say he's definitely having up and down days. There are days when he's chatting away like the old Nat and other days when he just can't find his words. He hasn't done any walking for two days, and he seems to be having difficulty pooping without pain. I wasn't entirely clear what the problem was. Brian said something about needing lots of diaper cream.
