I get very bad motion sickness whether it be on the plane, train, car, or even on certain rides at amusement parks. I always have to sit in the front seat when traveling by car somewhere far otherwise i get nauseous/headache, and end up vomiting. When i travel by plane, i always concentrate on music or a movie and try not to think about my motion sickness. But honestly Dramamine works so well!!! I always take it when traveling because it really works! But beware it will make you drowsy and probably fall asleep. They make Less Drowsy Dramamine too so check it out. Best of luck!!!

Bonnee is a 24 hour motion sickness pill. works great... I use it all the time when I fly... usually only take 1/2 pill... it will make you sleepy... there also is a patch from a doctor you can get... check with yours...

I have the best answer for you.
I used to get travel sickness on planes too, untill i tried chewing gum while on a plane.

if the doesnt work have your window open in the plane and keep walking every 30 minutes.
