Ok, so ive posted a few messages over the last few days explaining that its been a while since ive had a bm, 7 days now... I have been given some lactose solution from the chemist earlier today and have taken two 15ml measurements of the medication, has anyone else taken this for IBS-C? and how fast did it take to work, im in alot of discomfort, im drinking tea and hoping that will also help!!
