That was me, too...also incontinent during the day....for 13 years. Undiagnosed pouchitis. I had my pouch for about 10 years before the problem started. I was put on Flagyl (antibiotic) for 3 weeks but my symptoms were virtually gone in 8 hours!
Get it checked out. Not sleeping and pooping on yourself is for the birds, on many levels.
Hope you find relief and rest fast! Let us know.
