I too have a torturous . Showed up on my last 2 colonoscopies, 2021 and 2023. But been causing problems since August of 2022. I drink more water, try to walk at least a mile a day, (was very sedentary), and increase my fiber. I too felt so uncomfortable after my evening meal, especially if I happened to eat more than normal. I do not like taking MiraLAX daily, and not sure adding fiber helps me. Especially when everything appears to get stuck right after I eat. I slept only on my left side for over 2 years, because of back issues, but have been sleeping on my back and right side a bit. Has not seemed to make it worse. I am looking for something more natural to work. May try the warm prune juice I saw recommended. My work schedule does not allow me to take MiraLAX every day – but I cannot seem to get completely away from it. I do use Smooth Move tea on occasion. I do like it but again, don't want to rely on it either. I feel like I can say this here, I feel like I have never pooped so much in my life since my colonoscopy and after having taken MiraLAX for 3-4 months before the colonoscopy. I had severe constipation as a child, but not so much or so bad as an adult. I massage my abdomen and put a heating pad on it some evenings right before bed. That feels so good. Still searching for natural helps other than what I am already doing. Best wishes for you.
