Two recent posts at Health Rising, ‘Biomarker…‘ and ‘System Reset…‘, explore the role of the autonomic nervous system in ME. The research they describe definitely resonates with my own experience. I can get stuck in a state of ANS arousal that nothing seems to shift once it is in place–which is just as described.
One mind-body technique I have found helpful, where others have not been, is the Attention Training developed by the founders of Metacognitive Therapy.
I’d definitely like to try the non-invasive vagus nerve stimulation though!
