The little patch that goes behind the ear is called Scopalomine (sp?). The secret to using it is placing it behind the ear for 12 hours before going out.
My ex-wife used to get seasick (and carsick) pretty easily. She tried most remedies. Beleive it or not, the one thing that really worked were those wrist band with the little ball in them. You put them on according to the direction and they put pressure on a nerve that will reduce or eliminate seasickness. It actually worked for her! Wish they made one to go around her neck!!!! OMG did I type that outloud?? Sorry!
Hope this helps!
