It's not even confirmed if I have IBS or not yet (though I have just about all of the symptoms) but at one point when I was getting the pains, even though they moved around the abdomen whenever they were slightly to the right I became paranoid that it was appendicitis or something.However I knew I was being irrational but couldn't stop myself, but I had read a book by Paul McKenna on hypnosis and self hypnosis and I actually used what I had learned to hypnotize myself to stop me being irrational. It seemed to work, it at least calmed me down.So yeah, it seems it'd be worth trying.
