Hoss very interesting. I had vagus nerve condition vasovagal syncope. The doctors have said it believed the vagus nerve was overreacting to triggers. One cause is stress related to trauma that causes the vagus nerve to overreact. I gather the techniques to stimulate the vagus nerve is to normalize--restore the correct tone. Now after talking with the doctor who treated me for the syncope and other doctors it is helping to understand I have had symptoms for 20 years and due to my silence of CSA the syncope's root cause was never known. Thank you for sharing.
