My husband has it fairly bad. He ALWAYS has to drive (which is fine by me) and cannot go on any amusement park rides, no way on helicopters and has to take drugs to step on a plane. We were in Hawaii and both wanted to take a helicopter ride over the waterfalls, etc and he backed out last minute because of his 'issues'. We will probably never go on a Cruise for this reason.
Though, his parents have a motor boat and he has no issues on that. Interesting.
