im not sure dawn, if your not in any pain, i wouldnt get too worried, are you usually ok, or do you have probs normally. probably the best thing to do is to ring your dietician on monday, unless anything changes in the meantime. if you have any out of hours numbers, i would ring them. personally i take laxido now, which is another form of movicol, has this been mentioned by your team. i would just see how you go, and get in touch on monday.
