There was a thing called OtoTech talked about on Reddit years ago that I think people were making DIY versions of. It was supposed to cure motion sickness without using electrical stimulation I believe, but it's been a long time since I've looked into it much and the company never made consumer versions but stuck to military and medical stuff.

I was excited about this too! They're going the FDA route so expect it sometime before the heat death of the universe, if your insurance covers it. https://otolithlabs.com/
