I had it 18 months ago. For 6 months i was on various tablets, fibrogel etc and then an exclusion diet after i'd begged my gp to refer me to a specialist. I think a combination of high stress levels and gastro entiritus brought it on in the first place. I had a break from working and started going swimming regularly and over time my digestive problems have gradually eased. Now it appears to have completely gone and i can go out enjoying myself once more.
