I definitely notice a big difference in being able to hold my bowel movements even when pouchitis is flairing. I also am able to keep my appetite up so I don't lose so much weight while flairing. My bowels honestly feel better and are more manageable when I am using cannabis. Without cannabis I would definitely be in a bad place, weight loss and having trouble gaining any back was a huge struggle that is easier now. I also find it helps me to sleep almost all night sometimes (10pm-8am), besides just making sleeping easier I just have less bothersome bowels at night.
I hope that was helpful. I'm not saying that it's for everyone, I haven't been a user all my life but I am willing to try anything that works, which is how most of us got here. Good luck!
