My husband is extremely sensitive re motion sickness. Primeval Hurl knocked him out for a couple of days... He has used ginger and seabands for some time as he does not want to take any pills. I bought him the Relief Band on Drugstore.com after reading about it here. He actually was able to ride Expedition Everest wearing it and felt ok after a few minutes. I was still feeling a little dizzy (the backwards part) after about 15 minutes so I wore his Relief Band and realized after about 5 minutes that I felt fine again. The best part about it is not the avoidance but the relief.
