Take a book or something to take your mind off the pain. Unfortunately, you may just have to wait. Sometimes, the pain is not going to go away until you throw up. Be ready as soon as your stomach cramps begin, but only induce vomiting if the pain has not stopped within 2-3 hours.  Though it won't be your most fashionable accessory, keep a bucket or other container nearby. You'll be grateful you don't need to run to the bathroom. If you still have pain in 5-6 hours after vomiting a few times and eating something, call your doctor. Take your temperature and monitor your other symptoms, too. Though motion sickness is a very specific thing, once you're already sick, motion does you absolutely zero favors. Lie down and get comfortable. If that's not an option, stay as motionless as possible. This goes for babies and children, too. All ages will benefit from outside stability when the same can't be said for the insides. If the problem persists, your upset stomach is just a symptom of a grander issue. If you experience nausea for an extended period of time in addition to other symptoms like pain, trouble walking, and rashes, call a doctor immediately. Most upset stomachs resolve themselves within a few hours. If yours persists, look for other symptoms. If they are present, you may want to consider a doctor visit.
