While I love roller coasters, I become really, really sick about 95% of the time. Many people have suggested Dramamine, but it knocks me out like a light. Therefore, it kind of defeats the purpose of me even GOING to a theme park. Honestly, the best thing for my stomach (personally) is to have a BIG breakfast a few hours before going on any rides. Then once the day is over, I eat a huge meal. If I eat anything during the day (aside from small snacks), it comes right back up. Of course, these are just things I do. I've suggested these to other people and they look at me like I'm psycho. LOL.
