is a fan of the Alpha Stim device. This past weekend I got the try the Nuropod (ear-electrode vagus nerve stimulator) for sleep/HRV/nervous system regulation. I know many of you use Alpha-Stim (cranial electrotherapy), from my understand the technology used by Nuropod has a more different influence on vagal tone because it uses transcutaneous auricular vagus nerve stimulation (taVNS) vs the Cranial Electrotherapy Stimulation (CES) used by Alpha Stim. Does anyone here use Nuropod? And for those who have tried both, how would you compare?
