Remedies for seasickness
The best way to deal with seasickness is either get your body to be on a stable / static plane, or change your eyes focus to a static object, or do both.
Better would be to lie on your back and shut your eyes. This will free your brain from interpreting multiple visual points of references randomly.
If you are a voyager, or a sailor, then you can get yourself some handy practice to deal with this by doing some surfboarding that continuously changes the center of gravity of your body. You can even try sitting facing the opposite of the direction of a moving bus or car, and start looking at randomly changing things.
Try deep breathing exercises. It will help you to deal with nausea better. If you are stuck on a ship that rocks like a cradle then try moving to the middle of the ship, to get a more stable setting.
Drink lots of water.
