Hi Danman, nice to hear from you again. Seems like you're making good progress and the important thing is not to give up too soon. Even with nerve sparing, it can take two years to recover, and I have heard reports of recovery taking as long as four years.
Like you, I'm using the VED and injections. No Viagra or similar. Having sorted out my technique, I am now having 100% success with the injections. So even if I have to inject the rest of my (active!) days, I don't see an implant in my future.
I hang out in other forums and those who have had implants all speak highly of them. So they are certainly an option for those who have given up hope of a natural recovery. Enjoy the Tuesday lunch, and please do let's know what you discover.
