What usally helps your symptoms? If anything ever helps, could you doing while travling? If your problem is the interstate making you dizzy, I would take the extra time and go the back roads... Other than that, I really don't have any advice. I hate travel The going half way: YOu would know best with your body, personally it wouldn't work for me. I would sleep for days. but we are all so different that it could be the absoulte best thing for you. Hope I helped at least a little. -M
