There are all kinds of anti-nausea medications and natural remedies out there, but not all of them work quickly (if at all). Acupressure has been proven effective at reducing nausea almost instantly and, luckily, it's something you can do at home. Grab your wrist with your other thumb and first two fingers (your thumb should be pressed into your inner wrist, right where your wrist and hand connect). Press firmly, but not painfully, for 30 seconds, then switch hands. Repeat three times on each wrist. Instant nausea relief!
