This is an old and long thread, to which I believe I posted my experience. In a nutshell, I get sick sometimes, no telling when but usually not in heavy conditions or light conditions, but instead moderate conditions. My theory is that in heavy conditions I am too distracting by running the boat to even think about getting seasick, and in light conditions I don't have any expectation of getting seasick, but in between those extremes I have plenty of time to ponder whether there is any hint of oncoming seasickness, which becomes a self-fulfilling prophesy. So, my experience with the various remedies by only be applicable to people like me whose seasickness is psychologically induced. I have tried everything, including bands, but nothing works consistently. The patch didn't stop me from throwing up while scuba diving 60' under after noticing the undulating eel grass and immediately worrying about getting sick underwater, which hadn't happened to me before. (Turns out, no big deal, just like they teach in diver cert class, everything goes easily through the regulator. The surprising part was how many fish came instantly out of no where to feast on my misfortune.)
The bands remind me of a time that one of my buddies got sick and wanted to try them. We got one strapped on his wrist set at the lowest setting. He immediately complained that it wasn't strong enough to do anything. So, we turned it up a notch but he was still not satisfied. After a couple more ineffective adjustments he said "just turn it all the way up", which we did. Every half second he got a big jolt that made him really jump in agony and he pleaded for us to turn it down. The problem was that he was jumping around so much that we couldn't get a hold of him to make the adjustment, though finally we did. The amazing part is that it cured his seasickness for that day.
