If you have a history of panic attacks you could always talk to a doctor before hand. They might have some ways to help you to calm down if you are having on/getting one. If you really want to go on some for the thrill rides. But if that is not an option I would not recommended going on them.

Isn't the "chicken exit" the accomodation for those who suffer from panic attacks in confined circumstances?
