We swear by Relief Bands. They are worn like a watch but on the inside of the wrist. They work with a watch battery. You turn them on when you feel you need them and can adjust the impulse. It feels like a little twinge on the inside of your wrist. Within a few seconds, the nausea is gone. It is the only motion sickness relief approved by the FDA. They are expensive, (about $79 for the reusable one) but worth every penny. They are also great for car and ride sickness as well. DH and I bought them for our 7 day western last year and we are buying 2 more for the kids for our 4 day Wonder trip.
