I've tried all sorts of the remedies since I was a kid. I get sick when its flat and calm if I'm underway for more than half a day. I do best when we're bouncing around and there's a good breeze. Looking at the horizon is a key for me. Got the same advice as mentioned here from an old salt when I was a kid.
What worked for me was the patch (dry mouth was the side effect). I've tried the wrist bands, and Bonine or Dramamine. For the last two I learned not to take more than 1/2 a pill at a time otherwise I was so sleepy I was wasn't much help.
These boats ride like a cork, you get used to it most of the time.
