I'm an IBS-A and sometimes I feel like a yo-yo! I can't offer too much advice on IBS-c and bloating, but the fennel tea is pretty good. Perhaps others who are C can help out more. Have you tried other Soluble Fibre that does not contain white flour or sugar? People on Low glycemic diets have done this diet and have had some success. Have you been exercising regularly at a gym or at home? It helps a lot with the IBS.
From what you have said in your posts, it seems like stress is a major issue for you. Perhaps the hypnotherapy can help you out in that area. Another thing I want to add is that although I do watch what I eat and I'm careful of triggers, I don't obsess over what I eat. When I used to do that, it would stress me out even more and cause my IBS to be worse. Probiotics also helped me out a lot. Have you tried taking any yet?
