I can't do any motion simulator ride without nausea, and roller coasters just terrify me. I finally went on Everest a few years ago, and I lived! My ds had to pry my fingers from the bar to get out, I had absolutely no saliva left in my mouth, and my voice was hoarse from screaming, but what fun! I immediately went on it again - yes, round two. This time I had the first 3 side effects plus a ghostly pallor, the inability to blink, or to walk in a straight line, but I lived again! My fam thought I might be in shock, so they plied me with water. We went about the rest of a lovely day in Animal Kingdom. Another day back I rode it again - side effects slightly less, and have found my limit is twice in a row, then done. Love that ride. My sons won't let me ride RnR, I would probably be ruined for the day (loops and such). Rode Space Mountain once, too bumpy for me, but fun. I love Test Track and Thunder Mountain a lot. Anything that spins makes me sick. I always bring crystallised ginger to chew, sugar free mints, and ginger tea to add to hot water if needed. In case of super nausea, my ds gets it from his meds, his doc tells him to take Benedryl (yep, works amazing for nausea!) but that is only if it has already begun, as it can make some people drowsy. Good Luck!
