I have the exact same problem as you. Within weeks after takedown, I was only going to the bathroom like 2-3 times a day. Stool is almost always thick. Sometimes formed pieces. I strain terribly. No stricture. Surgeon says it’s a sphincter issue. But the strange thing is, I don’t feel like I have to go very often. Like it’ll have been 9 hours or longer since a bm and I’ll feel fine, like I don’t have to go. But I’ll try anyways bc I know there must be stool in my pouch. When I try to go, some will come out and then I’ll use a tap water enema and I’ll fully empty out. I also use miralax once a day. Did you say you take it 3 times a day!? Maybe I need to do that lol. I can’t figure out what my issue is. I know it’s not normal to go only twice a day!!
Maybe you should try Oatmeal too, I suggested oatmeal to him and he said things are much better. Maybe you should try too
