It really depends on what your issue is. I can't ride SM or RNRC because they just jerk me around too much and hurt my neck and back. EE and Guardians make me nauseous unless I take Bonine. So does FOP by the way. I've gotten now where I take it the night before my trip and every morning after and I'm fine to ride everything except SM or RNRC. I do close my eyes on the backward park of EE, the one on Guardians doesn't bother me if I take Bonine. Bonine doesn't make me sleepy, the trick (for me at least) is to make sure I take it the night before to start it in my system and to be consistent about taking every morning after wards. I learned this the hard way the first time I went diving in 7 foot seas and learned you can indeed throw up in a regulator at 50 feet under the water. Tron doesn't bother me at all. Oddly enough, I don't ride MMRR very often because the dance scene throws me around too much and one other scene makes me a little dizzy, I can't remember exactly but I think it's the tornado scene.
