Re: You sit there for sometimes hours without any clear "signal" that it's over, and when you decide it is time to get up half the time the act of standing opens you up again for the next bout.

I know you didn't intend to say something funny, but I had to laugh reading your reply and the whole description. I'm sure many of us can relate, LOL! I've been there--I have stomach problems for years and IBS. When my stomach is bad, so is the IBS and I'll be having alot of pain and spasms. I've had a sigmoidoscopy before, and compared that to having a baby. At least that's what I felt like afterward. I've known a few people with colitis and how awful it can be for them. Hugs go out to you!
