I personally can vouch for the ginger chews. I think they are made by the same people. I have never tried them to avoid getting queasy on a ride, but they worked great through 2 pregnancies and for carsickness. I have also recently seen a study on the effectiveness of ginger in capsule form and it proved that ginger IS an effective way to prevent nausea. So, I say, give it a try. It won't hurt and they taste yummy!
