You've probably heard more than once that having a cola can relieve an upset stomach. There's no real proof that this home remedy works consistently. But if it does work at all, it's likely because of the carbonation, and not the cola per se. When you're nauseated, your stomach stops emptying and fills with gas and fluid. Drinking something carbonated will help you belch, and that can release gas trapped in the stomach.
