@KaBoom - Reciprocal inhibition does sound rather upsetting. Depending on your phobia I would urge you not to write it off completely though.
When I was in college I worked as a receptionist at a psychiatrists office and he always reported very good results with this kind of therapy. Apparently it was especially effective on people with germ phobias. However, he said it was difficult to get patients to actually agree to it and I can understand why!
