Mrs Brian has a digestive condition that causes nausea. She uses Scopolamine skin patches and says they can help if she remembers to use it early enough. I told her about this thread but she didn't sound too interested.
I am not terribly prone to motion sickness but have been seasick in a small rental boat out of Neah Bay that was leaking from a missing seal on the bow eye and had to take my eyes of the horizon to bail water. I once got airsick on a business trip in a commuter turbo prop while passing through a thunderstorm. It was tough to have to service Customers that day.
But the worst was while I was a weapons avionics tech assigned to a NORAD fighter squadron for 7 years. I was reenlisted by the Squadron Commander during a ride in the back seat of a T-33 Shooting Star 2-seat jet fighter trainer. After I swore the oath, he asked if I wanted to do aerobatics. I hadn't been briefed and checked out for aerobatics by life support when getting my flight gear so it was a BIG mistake to say...
"
Lets see what this baby can do." Hoo Boy,
Wrong answer!

I didn't pass out, maybe because I was wearing a g-suit. I did puke my guts out and felt sick all through the next day.
About 4 years later I did go up again with the Squadron Maintenance officer for an NCO award "attaboy ride".
Once airborne he asked "Do you want to do aerobatics or fly vectors?"
My response was immediate... "
Vectors Sir." He gave me the stick and coached me to fly vectors around the Olympic Peninsula until we had to return to base. No airsickness that day! Fun time ✈

But I may buy Mrs Brian a Reliefband anyway because while she does not have dizziness with the patches it could have some cumulative side effects.
Plus I can "borrow" it if I go out with a guide.
