Okay so here is another angle I thought of to help explain the root cause that came up in another thread.
If you look at all of the systems in our body that are affected, the nervous system is the only one that is stimulated or over performing. Every other one and the symptoms that result are because that system is under performing. Can you guys see this? Can you deduce that the likely reason for the under performance of these other systems is due to a sympathetic nervous system?
