My work suggests melatonin is our natural narcotic. In the JAMA tilt tests, people with CFS, experienced symptoms quiet similar to those of people who have taken narcotics, i.e., nausea and vomiting, sweating, light-headedness, etc. These are also symptoms of syncope caused by neurally mediated hypotension. They are also symptoms of viral infection. I suggest they all are produced by too much melatonin.
Narcotics mimic the effects of melatonin.
A symptom of CFS is unrefreshing sleep. I suggest chronic fatigue syndrome results from DHEA insufficiency. DHEA taken orally in the morning may alleviate these symptoms. DHEA is currently available in a specific form that produces physiological levels of DHEA in the blood, and is available upon prescription. Added in Support of Above Int.
