Hello Colm, Vagus Nerve seems very critical. I am convinced now that 'Growth factor' deficiency is at the heart of POIS. Vagus nerve is critical to stimulate Growth factors and Thyroid which have systemic implications from digestive tracks, vocal and speech organs, and the Brain. Our principal problem is energy production/storage impairment. And this produces cascade of issues for us, one that our epithelium across the body is thin - which predisposes us to allergans like 'semen', to the fact that our body's ability to rapidly replenish following ejaculation is impaired.
While this tens unit is great, the 1000 dollar question, "how to in a clinically significant ways stimulate Vagus Nerve". Would you or someone know where these electrodes exactly are placed at??? When I research, I dont see effective ways, other than to implant a stimulator inside your neck (which I dont want to).
