If you will be able to sleep better in business class the answer is yes. I have terrible motion sickness although rarely on planes (thankfully!). I find the best prevention and remedy to be sleep. Outside of that, half a Dramamine. I've heard of bands but never tried as I though they were a joke. Based upon this thread, I'll give one a try. Would love to be a passenger in a car for once! (I cannot as I get terribly ill).
