Wow, thanks a lot, guys! I learned a lot of helpful tips. Never thought about the black pants or dog pads. I think I'll get one package of Depends briefs and some heavy pads. I also never thought of the brief underwear-I will definitely get a pack along with a couple of sweatpants as I don't own any. Good idea about the emergency pack in the car.
It took me a long time to decide between radiation or surgery, but now that I've made my decision, I'm eager to get it done and over with.
Thanks again.
