Hi Patricia, Just found your kind reply from July 17. Still having problems finding my way around this site. You sound as though in a short time you have had stunning success. I did as you suggested and downloaded Nenah Sylver's book (the frequency list) as well as the Cross Reference List. Many thanks. I would love to use the ulcerative collitis protocol for a client of mine but I am fearful that my license to practice psychotherapy could be jeopardized. Suggested she visit Chelsea's Sanctuary in Lafayette. They have the light, coil, GB4000 as well as many other machines for people to use at no charge. When you run frequencies do you do them daily or every other day? Jonnie
