When diagnosed with CFS, I didn't know anything about it. I immediately decided to learn all I could about this syndrome, and this book provided more information than I ever hoped for. The authors truly understand what it is like to have CFS, and absolutely validated my feelings and symptoms. The book offers information about prescription drugs, herbal remedies and vitamins that is thorough and helpful. I am glad to report that I am feeling much better after taking some of the recommended supplements, which are not mentioned in any of the other literature I found on this subject. If you are going to buy one book about CFS, this is the one to get. It's the only one you'll need.
