"our RO says in his experience almost no one continues beyond 15 -16 treatments."

Hey, thanks for that tidbit, Gail. I did 23 shots before stopping (for the second chemo) for a few days so now I feel better about that. My RO said I was much more persistent about it than most but, again, I wasn't sure if he was just trying to cheer me up. No one told me about the hydration thing but by the second week of rad they were giving me extra hydration every morning anyway thourhg the port so it probably worked out OK. Are there some kind of bad long term effects that can happen if you don't hydrate enough?
