Lizzie,My IBS affects me the same way. Right now I am in the C mode - very little, if any bowel movement for the past few days. I keep waiting for the "bomb" to drop, so to speak, when I will be spending most of the morning in the bathroom. Probably tomorrow when I have to take an hour + drive to my sister in law's!I have read on these boards about something called Equalactin, which is available at a pharmacy. I am giving this a try. Got to search and see about this pill. It may help.Good Luck.
