everyone gets travel sickness to one degree or another. put me in the back of a coach and I will be green. same as back of an aircraft or a car.
at the front, however, things change. it will go away in a very short time if you are driving..the coach; car or the aircraft.
if you are worried about your potential professional career, just forget the percieved problem - you probably have not got one (chronic afflictions apart).
good luck!
