Brian, for me the "mapping" was the worst part of the whole process so the rest should be a piece of cake. I'm now almost two years post-brachytherapy with no problems and no side effects. There are a few of us on this forum and our experience is pretty much the same...non-invasive procedure, little pain and back to action in a couple of days. You can read my "journey" if you are so inclined by selecting the link in my signature. Good luck and please let us know your progress.
