Hello and welcome to HCM. I fully understand your concern and I will try to write in a understandable way since you are asking to explain what a motion sickness is. It is a disturbance of the inner ear (part of our balance system) that is caused by repeated motion. The symptoms are a consequence of changes in sense of balance. Anyone can suffer in some point of their life from motion sickness. So you don t have to be worry about it. I would like to give you some recommendation to prevent or lessen the severity of motion sickness. - Do nit sit facing backwards from direction of travel - Sometimes it helps to keep your gaze fixed on the horizon or on a fixed point - Avoid strong food odors - Some over the counter medication are very effective in preventing motion sickness for short trips, like meclizine for example. Treatment of motion sickness is less effective than preventing it. I would recommend cinnarizine or dimenhydrinate as antihistamine medication. Regarding nausea I would recommend metoclopramide. Also caffeine might have alleviating effects. I hope my answer was helpful. Best regards
