Aaron, yes your friend quite probably will suffer from motion sickness. While some folks swear by the patch and the wrist bands som also swear at them. <G> It seems that many folks have good results with Bonine which is the brand name for Mesciline and that seems to work pretty well for them. I have heard that in rare cases it causes sleepiness but much less so than any of the other treatments. That would be my recommendation anyway.
