@Gargron would bet money this is vagus nerve related. Motion sickness is likely acting thru vagus nerve stimulation's impact on serotonin sensations from the gut-brain axis.
If so, long term use would reduce inflammation of the gut and might impact a bunch of other disorders.

(Of course there are different causes of tinnitus so I'd be curious to see if it works on mine 👵 )
