Hi thanks everyone.
HelloKitty-thanks I will look into that one. It says you're on no medication! That's amazing :)
Quincy-Is Actimel a probiotic? I am on that at the moment.
blueclassring-I have been told to avoid porridge, but white bread, white pasta and white rice are allowed (no brown). Low residue is basically very low fibre.
Alinus-I tried to PM you but could not find a way to do it. thanks for the advice though.
Everyone seems to recommend a food diary. The only foods I have noticed which do seem to affect me quickly are cereals and apples, which I used to love but cannot manage now unless cooked to a pulp. I was stupid once and ate a bag of coconut pieces, which caused a flare-up. Also large meals of any kind seem to set me off, especially rich ones like Christmas dinner.
