Acrophobia | Fear of Heights | Do you know how to cure this phobia?

Does anyone know how to cure this phobia? I certainly don't. We've tryed hypnosis with 3 different "therapists", one of them was even featured on 20/20 (A NZ show similar to 60 minutes) But I think the fear of heights has actually gotten worse!

Let me clarify, I am not the one with the phobia. That curse belongs to my partner. When we first met around 4 years ago he was fine (no phobias) we used to have lunch on the roof at work which was 5 floors up, then one day literally out of the blue he was in a hotel and started taking the escalator up to the conference room on the 3rd floor and had to go back downstairs as he started suffering vertigo. Since that fateful day it has progressively gotten worse. There were no more lunches on the 5th floor; he could only make it to the 3rd floor at this stage. A few months later he couldn't make it past the 2nd floor. Now 3 years later we can't even eat in a restaurant that is upstairs.

This means we can't go to the movies, eat out at a lot of places, park in car parking buildings, stay in hotels... the list goes on.

I would love to hear from others who suffer acrophobia / an acute fear of heights (not just those people that feel uncomfortable because they're at the top of a 50 floor sky scraper standing on a glass floor - that is NOT a fear of heights!)

I would love it even more to hear from people that have over come their fear of heights.
