Merkelman, thanks for the info on Hytrin, I will call Bob and have him ask the doctor tomorrow. He was up and down all weekend with urgency and didn't get much sleep. Have also noticed everytime he eats you can hear things turning and then we better be close to a bathroom. I have put him on mostly carbs and no fruit, veggies and juice. Lots of eggs, cheese and rice. If anyone has any suggestions for meals it would be great. I cook most of his meals ahead of time and he takes them back to our fifthwheel to eat during the week.
As for the fatigue I'm sure some of it is stress as you said. I did notice over the weekend doing yard chores he tired pretty easly and was pretty pale in color. Hope the next four weeks go fast and he has little side effects.
