i keep stumbling across TENS (electrical current) for vagus nerve stimulation but these things can cost hundreds of dollars (and i bet there is a reason for it too but i just can't afford that). there are cheap ones too, plenty even but i have no idea what to look for (except i want/need an ear clip but you can get those separately too, but then what's compatible with what?).
so i am looking for a recommendation for a cheap unit (preferably from aliexpress) with ear clip, please!
