Put the pressure on your pregnancy, literally. There's an area between the wrist and elbow on the underside of the arm that you should get familiar with. About 2 inches (5 centimeters) or three fingers above the crease of the inner wrist, in the middle of the wrist tendons is a pressure point that can be stimulated to relieve nausea. Simply rub it with your thumb for about five minutes, then switch to the other arm. You can repeat this as often as necessary, until your nausea seems to settle down.
You can also buy a band to do the work for you. For years, seafaring folk have eased motion sickness with elastic wristbands outfitted with a hard plastic button designed to activate this pressure point. Known under the brand names Sea-Bands or BioBands, these over-the-counter remedies can work on morning sickness -- sometimes in as little as five minutes after being worn over the pressure point.
