I'm going to Edinburgh at the end of this week for a holiday, but were travelling by car and I get very bad travel and motion sickness and from where I live it's going to take about 7 hrs to get there. I'm only 15 so I can't take the tablets that thin your blood to make you fall asleep, does anyone know any other remedies? Thank you.

What does being 15 have to do with what you can take to help motion sickness.

What other normal over the counter things have you tried ?

And no, you don't take blood thinners, where did you get that?
