I find it interesting that the CDC lists "weight loss" as a common symptom in CFS, but not "weight gain". I believe their rationale is that since there seems to be a viral connection with CFS, and most viruses including HIV, influenza virus, Coxsackie virus, Ebstein Barr Virus, etc. all cause weight loss. Do you feel that in general there is a higher association between CFS-ME and weight loss or weight gain? I hear both sides of the story: Some have gained a few pounds and others have never regained the weight lost from the onset.
