Hello,
I lost most (75%) of the nerves on one side also. They put me on Cialis as soon as the catheter was removed. I also used a pump to help with blood flow. For the first 6 months--nothing. It was like trying to shoot pool with a rope. Finally, the Cialis slowly but surely started to kick in. At almost exactly one year I was good to go without meds at all. My wife (9 years my junoir) takes full credit for my complete recovery
Good luck,
Tom
