Yes, it was definitely my worst ride experience. I am a super rational and logical person, but I was seriously starting to freak out. I felt like I was going to suffocate with no air (a fan blows during the ride to simulate wind) and was starting to break out into a sweat trying to breathe through the nausea. They were very quick (it was probably only 5 minutes or so), but it felt like forever.
That experience made me realize why they have all the warnings. I know I have motion sickness and claustrophobia, but I always ignore the warnings figuring I can manage it. Even though I know I can handle the duration of the ride itself, I have to consider how I would react if I was stuck for a while. That never entered my mind before.
