I know that it has been a while since you posted and I hope that you have found a solution. I just wanted to tell you about what helped me. When I was diagnosed with erectile dysfunction my doctor prescribed the pills for me also. Unfortunately the pills did not help me at all, I mostly got the side effects. After quite some time of searching for a solution, I found the Pos-T-Vac Vacuum Therapy System. All I can tell you is that it has made a huge difference in my sex life. I can now get and maintain an erection when ever I want one. No more worrying about whether I will be able to perform or not. It has really been a life saver for me. Hope this helps....
