As you will know with IBS, what works for one person, isn't going to necessarily work for another.  I would advise against dismissing hypnotherapy and CBT approaches altogether, as of key importance is finding a therapist with whom you can feel comfortable.  To help your research have a look at our Counselling and Psychotherapy; Hypnotherapy and Stress, Trauma and IBS factsheets. Included in those factsheets are details of all the professional bodies and associations through which you will be able to find someone suitably qualified in your geographical area and in an approach which aligns with your thinking. I would also reacquaint yourself with the self care programme as you will find lots of useful advice.
