I use the scopolamine patch when I go out on the ocean, or up in the Straits where there are ocean swells. It works well, leaves me with a bit of cotton mouth, but doesn't knock the crap out of me like Dramamine. I usually put it on the night before heading out and take it off on the way back to the dock.
A one day trial would be a good thing, it will tell you whether it works or not.
