Fatigue makes you more vulnerable to motion sickness. Avoid drinking alcohol before or during travel, and don't overindulge the night before. Read the package for cautions and other important information. Don't read while traveling and don't try to focus on any other stationary object. Aboard a ship, lie down on your back and close your eyes.
Some people report that taking tablets of powdered gingerroot relieves their motion sickness.
Others find relief by pressing on an acupressure point about midway on the inside of the wrist, where the hand and forearm meet. To settle a queasy stomach, eat dry crackers.
