Personally, I do not get up in the middle of the night, but I have been flaring quite a bit since May of 08. When do you take your oral prednisone? If you take it all in the morning, try dividing it, 20 mgm with breakfast and 20 mgm with lunch. Not saying this will do the trick but give it a whirl. I have terrible insomnia with prednisone.
What is your diet like? Maybe try a bit of fiber. Not all of us can tolerate fiber while flaring but it can add bulk to your stool.
My doctor wants me on the cort enemas, but they just ooze right on out. My problem is ulcerative proctitis. My script for Canasa suppositories was still good, so I am using them every other night.
I've had this disease for over eleven years and I can sympathize with you. If Humira fails, I am looking at surgery.
