Hi Rhonda,
Very often motion-sickness is associated with migraines. Do you get headaches as well? Migraine prophylaxis (i.e. topamax, beta-blockers, effexor XR) can help the headaches and the motion sickness.
As you mention in your post, the scopalamine patch can be very helpful specifically for motion sickness.
(Can you guess from this advice, as well as my handle, what I do for a living?
