Can't answer your first question, but just to let you know that my husband has had no problems to date with Levitra, but I think it is a bit of an individual thing and takes some trial and error in consultation with medicos as side effects are always a possibility. My hubby had headaches on Cialis, but not with Levitra. Oddly enough, Viagra had no response for us, but I am not sure if that was a time factor thing, as nothing was working at the time my husband tried the Viagra (at 4 months). At 7 months after surgery however, we started to notice some good response with Levitra so stayed with that one, and at 8 months Levitra 20mg was working well. We worked hard with our own ED rehabilitation plan using all the advice here from others about keeping up the stimulation and blood flow, and taking into account the experiences of all others with similiar situations and age etc. We consulted with the Surgeon both before and after surgery, and with a men's health specialist about 12 weeks after surgery.
Good luck to you and Mo.
