You guys may think I'm smoking crack or something but try putting a brown paper bag under your shirt. I work on a charter boat during the summer and a few people have done this and it has worked. The theory behind it is that the bag helps you keep your mind off track from feeling sick. There is also a little artice in Great Lakes Angler that I will try to dig up that talks about this method. First time I heard about it, I couldn't stop laughing. May sound crazy to you but its worth a shot.
