Have the doctor prescribe injectable relistor. This is literally the ONLY thing that will allow me to have a bm, and usually if I'm backed up which I always am, I have a bowel movement within 5-10 mins while drinking my coffee, and before any food for best results.

Have fought this battle for 20 years. My experience is everything stops working if used daily so I do hit and miss. Have found laying on stomach before getting out of bed, doing some relaxed breathing and focusing on relaxing abdominal area very helpful. Apples, Raisin Bran clusters from Trader Joe’s with added Sunsweet prunes chopped and blueberries helpful. Physician Choice probiotics (Amazon) at times. Drink cold water upon waking 16 oz though I struggle getting that much. The cold water stimulates the reflex in gut. Few things I do daily- Magnesium oxide 400 mg at night + 2 stool softeners. Pepcid AC has some fast acting magnesium that definitely helps getting started. There are definite floor exercises that help move things. On YouTube. Begin to really tune in to slightest urge and go to bathroom. It sounds simple but extremely effective. Could keep a food diary. Akkermansia is another probiotic that people swear by. Use it as directed. My back exercises on floor have definitely been helpful. When all options have failed I go to Magnesium Citrate. Clear liquid At drug stores. Used to be given to clean out for colonoscopy I only drink 2-3 ounces. Takes about 6 hours.
