I get travel sick, badly. I always have, and long journeys are a pain - I can't read, look at a map, play with phone - I'll get a weird zoned out feeling and will feel sick. I've got used to it and manage it so well (look straght ahead) I rarely am sick nowadays - but its been known. The kids have it too - not sure if they are as bad as me.
I've never mentioned it to the GP, I have tried Joy Rides, which made me feel as if I was off my face and not in a good way. Is there any decent treatment nowadays.
