I have had 14 (of 40) IMRT sessions to date and am having similar issues to what you describe. At its worst, I was peeing every two hours at night. Based on what I've read here and elsewhere, I'm glad I didn't get a prescription for Flomax. Instead, I requested Cialis but I have to say it is not very effective but maybe better than nothing. I have noticed that when I take ibuprofen before bed, though I don't like to take it, it reduces the number of times I need to pee.

I also have bowel problems from the radiation but it has greatly improved since I started a regime of a tablespoon of psyllium mixed in water in the morning. I also take retinol (Vitamin A) in the form of a teaspoon of cod liver oil every morning as well. This has resulted in a big improvement in bowel function.

I also try to get a workout in each day on a rowing machine. It tones the muscles in the pelvic region as well as elsewhere.
