"Had Brachy Therapy for Gleason 6 prostate cancer a couple weeks ago.  Am on the generic tamsulosin to relax the muscles and improve urinary flow.  Side effects for me have been diarrhea, and stuffed up feeling.  Sometimes the bowel issues and being stuffed up make it hard to sleep.  I suspect that tamsulosin exacerbates minor allergies and have to be super careful what I eat.  Am trying to avoid bread, sugar, and vitamins to see the impact.  Not sure it is doing anything for my urine flow, as I seem to be getting up the same number of times during the night, but I will stay on it."
