Wow, you have a lot going on. I got diagnosed a month ago. As long as I don’t get constipated I do ok. It’s a balancing act with water and fiber and food, and stress. I eat my main meal midday. I take food enzymes. I eat mushy food, think eggs, oatmeal with berries,yogurt. It takes a long time to empty bowels, 3 or 4 small movements in the morning. It keeps me from being in pain. Doctors have been no help. Linzess helps with peristalsis but I try to use herbal laxatives instead. And yes this occupies a lot of time at least in the morning. Good luck.
