I found the online pharmacy myself and it's great. The regimen for the viagra was set up by the Doc as follows: one pill daily and up to four more when you plan on sexual activity, no more than five a day. I have the philosophy that if you don't use it, you're going to lose it. At 61, I didn't want to call it quits and so far, the therapy has been effective. I no longer have to take additional pills to have sexual activity (I'm six months post-op). I continue to take one pill daily and because I have high blood pressure, miraculously, the pill seems to have lowered my B.P. to normal and I stopped taking my B.P. medication.
