I have no diagnosis, disequilibrium, but I do have ME. I fit the CCC. My gp hasn't heard of them. I personally believe it is a mitochondrial dysfunction, possibly a retrovirus in the mitochondria. It's the only thing (using Occam's razor) that would give rise to all the symptoms that appear. It certainly explains every single symptom I get. I do not think I have "CFS". CFS is just a wastebucket label.
