I was treated about 3 years ago, maybe more. My psa was about 11. I was treated with 5 cybercide radiation treatments. I need a little Viagra from time to time but I can function pretty well. To be quite honest I really don't think I need it. Not much anyways. I don't get tired at all and maybe that's because I exercise moderately at least 4 times a week. I don't leak at all, not even a drip. It seems that the only problem I had was with the medication for urine flow. I took it but it made me a little week and somewhat delirious. I still took it until I was convinced my urine flow was ok. My last psa check was a month ago and its down to 0.53. I'm very happy with my treatment. Keep in mind with radiation psa can bounce up and down a few times, maybe more so be patient and optimistic. You will experience bowel urgency in the begging for a week or so but then it goes away. Really it was a piece of cake.
