I am glad you asked. I was going to ask the same. Do you think closing your eyes would help if it were to induce dizziness? I was wondering the same for myself.
Yes, that is a strategy. Anytime there is a discrepancy is what the eyes are seeing and the inner eat is feeling, the potential for motion sickness exists. Simulators, roller coasters with twists, turns, or jerks, and spinning rides, and even being the passenger in a car (especially if you are reading a book or looking at a device) can all potentially cause motion sickness in susceptible individuals. If you are on a simulator type ride and start feeling nauseated or dizzy, you can try to close your eyes or focus on a part of the screen that is not moving. If you are not on a simulator, but a moving ride, it is best to focus on where you are going. For example, in a boat, look towards the horizon. Sometimes these counter maneuvers do not work, but they are certainly worth a try.
Aside from avoidance of troublesome rides, you can try the litany of motion sickness medications or saving the ride until the very end of the day to sleep off any ill effects. When questions arise over whether a certain ride will cause motion sickness, you are going to get many different answers based on an individual’s sensitivity. I’m a fellow motion sickness traveler and a pharmacist. I find the best strategy is to try each possible offending ride one time at the end of the day with the expectation that it may be the last time I ride. I am pleased that I can tolerate Soarin, Dinosaur, TOT, and RnRC (x2 only). It’s a no on Mission Space, FOP, Star Tours, Tea Cups, Astro Orbiter, Space Mountain, BTM, EE,... Everyone has there own list.
My advice for those who want to ride Ratatouille or MMRR is to try it at the end of the day once, and if you have found it helpful in the past, premedicate with your favorite medication. No one can tell you for sure whether you will experience motion sickness, but know the potential is there.
