Hi, I worked with one of his doctors - Larry McHaney. I talked to Dr. Larry Wilson a few times on the phone. all in all, I think it's a good program, but wasn't getting the results I wanted after two years, though I did have some improvements in energy. I think Wilson's site is a fantastic source of knowledge. I wrote about my experience on my site. Here is the page: http://www.amandashealthjournal.com/dr-larry-wilsons-protocol/
