Are there pressure points to prevent motion sickness?
It seems to for some people. My son swears by an item called Sea bands. They are an elastic wrist band with a smooth plastic button on them. Follow the directions to put them on. Put them on about 30 min before you go traveling and leave them in place as long as you need them. They are available in most drug stores or see amazon http://www.amazon.com/Sea-Band-Sea-Band/… The pressure point is approximately two fingers below the bend in your wrist and in the center of the inside of your arm.
