My son has a bowel disease and was using Mirilax daily. I used it for awhile but didn't notice much difference. I can drink magnesium citrate and that works but long term use of things like that can cause you to lose control of your bowels so it's scary. But after 4 days of not going, I drink a magnesium citrate. My body doesn't like a lot of fiber and those fiber additives make me sick. my sons bowel disease is not food related and I'm beginning to think the underlying cause of my bowel issues is not food related either. But some foods feel better to eat if I'm flairing, or I don't eat at all to avoid pain. My attacks last days and even weeks.
