Well, I've been on pred for a little over a week now, and boy, has it ever made a difference. I started last week on Monday and by Tuesday only had four BMs, which was less than half of what I'd been having. Since then, I've only had one or two BMs a day, and they've been normal consistency since Friday, and that's even with adding lots of fruits and veggies back in my diet!! :)
It's just weird, though, actually having to work to get poop out again! Even when my symptoms mysteriously eased in December (before I was diagnosed), I still had really loose stool, so didn't have to "work" at it.
