I had only been sent to the right side before our last trip, and I considered it a 4 motrin ride. Almost as bad as the wooden coasters. In January, DD9 and I rode it and got to go left. Soooo, much better. Still a bit jerky, but no headache/neck pain afterwards! I even voluntarily rode it again 2 days later (also left side; we asked for it that time!). We were also in the front car on both those rides. I love RnR....as long as we are in the middle or front. Back is no bueno.
