Patients who experience the urge to vomit while riding in a car indicate the occurrence of motion sickness and a more sensitive vestibular function. Patients are advised to take a good rest and not to look out of the window. It is better to lean the head against the back of the seat, which can effectively prevent the aggravation of nausea and the desire to vomit, and to eat some acidic foods such as prune candy and oranges, and also drink apple cider vinegar and lemon juice.
