What do you do about constipation? I have always had a problem since MS, but the older I get the worse it gets. I take a lot, (a lot) of fiber, use stool softeners, but nothing seems to work any more without using a laxative or something that will make me go. I don't know what else to do. The fiber just gives me lots of gas and doesn't help. I drink lots of water. What else can I do. Help.
