The usual treatment for spasmodic pouch isn't Flexeril. It's anti-spasmodic meds like Bentyl and Levsin. Are you treating with someone who is experienced with J Pouch treatment issues? I had similar issues after takedown and Bentyl and Levsin taken 45 minutes before meals resolved them. Whether a component of your issues may as well be due to pouchitis is unclear, but the sense of incomplete evacuation was something I had with pouchitis, not spasmodic pouch, which I had soon after takedown and is very common.
