Well, I think everyone has a different remedy. I was in Cabo last month and did fine out in the Pacific. I just poped a few Dramamine in the morning. If I ever start to feel ill, a nice cool breeze and drinking cold water helps me. This might sound crazy to alot of you but last year I got a little ill feeling and I leaned way back in my chair, closed my eyes and just went with the waves as the wind was blowing by. Motion sickness is caused by vestibular disorientation, where the semicircular canals of your inner ear sense motion and send that information to your brain and becomes confused by the information it is recieving from your eyes. Knowing that, I figured I could remove the visual signals my brain was recieving. Seemed to work, I didnt vomit!

Im sure fishinphysician can do a much better job of explaining this, and probably even correct me.
