I get these symptoms with pouchitis. I get the waves of gurgling and very loud noises in my pouch with cramping until I empty it it and also struggle with repeat trips, not fully emptying, straining, repeat trips and lack of sleep at night. I have not slept through the night since having my surgery and I envy those who can. I have just developed a very high tolerance to all this stuff as I do not want an ostomy, but I know I could never, ever hold down a job like this. I have found at night a warm water enema really does help empty me out and provide me with at least 4 hours of uninterrupted sleep. I reserve this measure for when I am desperate though.
