I'm one of those despicable never-get-sick types like Big-T, but my wife has always been a miserable boat passenger. She tried Ginger, Scop patches, Bonine, Dramamine and VooDoo. Nothing really did the trick for her. The only real solution we've found is the
Relief Band.
This sounds like a commercial, but all I know is that it works. And what's nice is that a person can use it
after the onset of symptoms, unlike any of the drugs. So, in my wife's case, if we're cruising out to a divesite on glassy waters, she starts off not wearing it. But if the pitch and roll of breakers gets to her, the band goes on and problem's solved.
Check out the site, apparently there's some science behind the device, and it can work for any kind of nausea including Morning Sickness. Expensive bugger, though.
Good luck pukers!

P.S. I recommend the battery replaceable version, and don't pay retail. There's plenty of sources for less.
