It has been 3 years since my HDR Brachytherapy, and Viagra still works for me, although the day after, I have problems with stomach cramps and diarrhea.
I have found that I need to take it on an empty stomach to be effective, and I have tried taking Pepto Bismol tablets beforehand, but it really doesn't help.
Has anyone else had this problem, and have you found anything that can be done to reduce this side effect?
