Stop motion sickness

A commenter reminded me of something: ginger can combat motion sickness very effectively for some people. If you are going on a cruise, bring some just in case (maybe in crystalized form so customs doesn't get wonky about it). I, myself, can take the movement on a cruise, but it gets irritating when the ground is still moving 2 weeks afterward. I've found a nice cup of ginger steeped in hot water ends that problem.
