I do EE with no problem but can not do RNRC. The first jump start throws my head back no matter how hard I try to keep it on the back to start with then during the entire ride my head is bounced around back and forth, again I try to keep it pressed to back head rest but I'm height challenged and not very heavy. When I get off it, I have a horrible head ache and my neck hurts so I just don't do it any more, I can't do Space Mountain for the same reason. I don't do Star Tours because the 3D makes me sick (I don't actually throw up) and don't do mission space for the same reason. I can do Soarin with no problem and actually had my first decent ride after 4 tries on FOP a couple of weeks ago. I love roller coasters but as I get older, the shaking is what bothers me, the old bones just aren't what they used to be.
