This can last for a few hours then by evening I get ibs c again. I have had occassional D in the past, but never as often as this. I have eaten a lot of biscuits lately, which is not my style, as I am very strict about my diet usually!! But even when I've not eaten tham, I get diahorrea. All this is really getting me down as I have accepted my iBS over the last 7 years and do all I can to be positive and work with food elimination (apart from the recent splurge!) Can it just change like this so fast?? Any help would be more than welcome. It is really upsetting me at the moment. Many thanks.
