Ouch!I read that VNS should occur on the left side of the neck to avoid any heart issues. This is the reason I have not tried to self hack my vagus nerve with my Tens or Liss. There is one report of death I read from auricular acupuncture to stimulate the VN (might have been the right ear, I can't remember).
In his GWS study Natelson is having them use the GammaCore device on both sides of the neck by the way...
A POTS study using vagus nerve stimulator should be coming out pretty soon. They couldn't get a company to give them a device so they had to build one of their own (lol)
