I became sick in September 2009. After seeing a chiropractor/neurologist, two family doctors, two neurologists, two endocrinologists, a pulminologist, and a cardiologist; I ended up at the Mayo Clinic in Jacksonville not knowing what was wrong with me. At least the internist there (Pedro Malavet) gave me a diagnosis of chronic fatigue syndrome. None of the other doctors prior to that even mentioned it as a possibility. Also partially to his credit, he emphasized graded exercise therapy and did not even recommend cognitive behavoiral therapy. Needless to say, GET didn't work for me. Clearly the Mayo Clinic follows the British model, and they are very behind the times. If you know that you have chronic fatigue syndrome, don't bother going there. Stay away as they cannot help you. They put no emphasis or focus on it.
