Thought of travel sickness makes me sick! Why?!?

I've been looking online for travel sickness remedy that I'm going by train next week and the coach and on a bus. I found the drug to pharmacists, shops and doctors not work and the little bracelets / bangles. While I've been searching online for other peoples suggestions I found that I begin to feel ill. It's a bit strange question, but I'm just curious why this would happen! Also, if you have a remedy that might work could be useful! Have had the disease for travel pretty much in my life and I thought it was something that I grow.

youre ahead this, so your mind becomes insane, and think your travel by car, plane, train or boat., relax and do some deep breathing excersize .. it should help.before you go there, eat lightly and take dramamine, thats a bad pill.have a good time.
