Probably not to many freshwater guys who know much about seasickness, it’s prevention or cure.
I’ve got one kid who could get seasick in the bathtub and bought him a few boxes of the scopolamine patches about three years ago. They certainly work (unlike most of the stuff on the market). A year ago the guys in our game fishing club tipped me off to compounded scopamine tablets. They work even better, they’re cheaper and that’s all we’ve used since.

The yanks also use it in a nasal spray.
If you’re struggling to find it on your side of the pond I can probably get some to you. I’ve mailed the pills to friends in the states before, usually takes a week to get them. Idk how Canadian gestapo (customs) would react to the pills though, might have to send them with a mule.
