I would be curious to know which vagus nerve stimulation device you use, and if it helps you.
I used a Gammacore, and now use a Truvega, which is the over the counter version. It seems to help me a little 2 get through the sleep inertia I have after napping. It may have helped more, in general, with fatigue, when I was doing 4 stimulations 4 times/day. They my bad I got lazy and now use it in th morning, within an hour of getting up, and if I remember after a day nap.
