Duck,
Your profile indicates that you had J Pouch surgery in 1999. Has this situation been going on for 20 years? I think we need to hear more about your history with obstructions. Without hearing more, I would not be so accepting of the doom of the “learn to live with it” diagnosis. What you are describing is a major quality of life issue, possibly fixable although I don’t know that. It’s very tough if you can’t work consistently in any business and certainly more so when you are self employed. Good luck-
