My experience with Compazine was many years ago, but it was so horrible, it is still vividly etched in my mind. I had a severe panic attack reaction, but it was not just anxiety and jitteriness. It was this excruciatingly unpleasant sensation of being "suspended", like the way you would feel the first second or so after jumping out of an airplane or from a high building, except it goes on and on for hours. There is no "settling down". It was horrible. I'd rather die than take it again.
