After re-reading this tread, I came to the conclusion that we are not all the same...
It is necessary to distinguish between the different kinds of dysautonomia groups in ME/CFS.
I think that there are two main groups in ME/CFS: Sympathetic dominance (with a decreased parasympathetic tone) group and a underactive autonomic nervous system group.
I guess that most ME/CFS patients have an increased sympathetic tone and a decreased parasympathetic tone.
Symptoms of sympathetic dominance:
*Paleness (sympathetic dominance decreases skin blood flow)
*Gut problems (sympathetic dominance decreases gut blood flow which results in gastroparesis, malabsorption, dysbiosis and leaky gut)
*Immunosuppression
*Excessive sweating
*Anxiety
*Increased (nor)epinephrine
*Irritability
*Exacerbation of symptoms by stress, cold and exercise.
Therapy:
*Deep breathing, Meditation, Yoga (decrease sympathetic tone and increases parasympathetic tone)
*Muscarinic acetylcholine receptor agonist.
*Beta blockers
*Alpha 2 agonists
Therapies that increases acetylcholine will promote the parasympathetic tone (good thing) but also sympathetic tone (bad thing).
The therapeutic effect will depend on how much each systems is stimulated.
The second ME/CFS dysautonomia group, the underactive autonomic nervous system group:
Symptoms underactive parasympathetic nervous system:
*Urine retention
*Constipation
*Decreased salivation
Therapy:
*Urecholine
*Huperzine A
*Choline, Citicholine, L-Alpha Glycerylphosphorylcholine
*Cholinesterase inhibitor
*Alpha Lipoic Acid
*Acetylcarnitine
Symptoms underactive sympathetic nervous system:
*Orthostatic hypotension
*Decreased sweating
Therapy:
*Midodrine
*Amphetamines
*Yohimbine
I guess, it's best to be guided by your symptoms...
