Motion sickness can be overcome through repeated exposure.

Not sure what sort of repeated exposure you are referring to.
Didn’t realize I had a problem. Had done OK growing up as a kid in small boats on lakes with minimal wave action.
However, when I went out with an organization President & friends for a day of sea fishing—the waves were going every which way on all axes. I was all heaved out and lay moaning on the bottom of the boat for 8 hours. They were not about to cut short their fishing for my problems.
I had taken anti nausea/motion sickness meds beforehand. Was absolutely of no use.
