Dr. Whiting (an orthomolecular nutritionist), finds in his work with people suffering with this that they are all very toxic. When their systems have been properly detoxified their symptoms will disappear. His personal feeling is that this is a condition of hyper-toxicity and manifests itself in people who are unable to physically cope with the overload of toxins in their system.
