In the words of the radiology NP-C I spent some time with, "Beans bad, yogurt good." What amazes me is that I'm not stressed about the fact I have PCa, or ADT, or radiology treatments, but I'm highly stressed about a daily bowel movement. The importance and the absurdity of this does not escape me. I found this site helpful.
