I suffer terribly from motion sickness, and as I've gotten older it only gets worse. Until I was 40 I had great success with Bonine. Since then I've moved on to the motion sickness patch, Transderm. It is by prescription only, and you really need to talk it over with your doctor as there are many side effects. One patch lasts three days. I still can not go on spinning rides like the Teacups or Star Tours, but no problem with any of the coasters.
