2 months post-op and have been on Viagra (50mg daily) since the catheter was removed. Sometimes my face flushes in 1 to 2 hours, sometimes I get no reaction at all. Is this normal this early? How do I know that it is effective? I'm somewhat confused at the moment. Prior to surgery I took Viagra occasionally. I usually got some flushing in the face in about
an hour accompanied by an erection. Anyone out there on rehab, taking Viagra with any advice? I sure would appreciate your experiences.
