To prevent motion sickness there are a number of things you can do:
• Consume foods and drinks that agree with you. Avoid excessive alcohol and foods or liquids that cause you indigestion, nausea or gas or make you feel unusually full. Heavy, spicy, or fat-rich foods may worsen motion sickness.
• Choose a seat where you will experience the least motion. The middle of an airplane over the wing is the calmest area of an airplane. On a ship, those in lower level cabins near the center of a ship usually experience less motion than higher or outer cabins.
• Do not sit facing backwards from your direction of travel.
• Sit in the front seat of a car.
• Do not read while traveling if you are prone to motion sickness.
• When traveling by car or boat, it can sometimes help to keep your gaze fixed on the horizon or on a fixed point.
• Open a vent or source of fresh air if possible.
• The over-the-counter medication meclizine (trade names are Bonine, Antivert, Dramamine) can be a very effective preventive measure for short trips or for mild cases of motion sickness.
• Your doctor also may choose to prescribe medications for longer trips or if you repeatedly develop severe motion sickness. The most common prescription medication is a patch containing scopolamine (Transderm-Scop). You would apply the patch about 4 hours before travel. Its major side effect is drowsiness.
