crackers. Stay hydrated. And whatever you do, don't think about pork chops and dirty ashtrays. No, seriously. When I am overcome with nausea, I focus my mind's eye on a tall, ice-cold glass of water. I envision the condensation forming on the glass, the clink of the ice cubes, every little detail. The mental image is so cool and refreshing that it seems to keep the nausea at bay, and it distracts me from the heaving deck and the bile rising in my throat. If all else fails, go ahead and lean over the rail. If you're like most people, after a couple of days of vomit and misery, you'll feel just fine. In a very few, extremely rare cases, some people never feel better, and just keep getting more and more sick, endlessly, into oblivion. In that case, I still think you should follow my advice: take drugs and drink alcohol. Just do it on land. I guarantee, you'll feel better right away.
