In addition to what has been mentioned you might also want to consider plain old Ginger Ale.
Accupressure works for some:
Most pharmacies carry wristbands with snaps or buttons. These wristbands are designed to press against pressure points in your wrist.
You can also try to do this by bending your wrist and measure three finger lengths of your forearm. Depending on the size of your finger, you may have to try to find the pressure point. Feel around with light pressure until you find a tender spot. This is the P5 point. The P6 point is about 1 ½ fingers back toward your wrist. You must apply some pressure hard enough to feel it, but not too hard causing pain.
Press on these spots for 1 minute and repeat 2 or 3 times, resting 30 seconds between each application.
Please know that results vary and given the severity of nausea caused by chemotherapy, sticking to what works well chemically might be best.
