I use Senokot which isnt the best choice I do get cramping but not that excessive bloating (looked pregnant and I am thin) and in terms of emptying bowel, works better for me (& other side effects)which never seemed to end. I have a script for plenacatide ($ 200 for 20 pills here in Canada) but had such a bad experience with Linzess which is called Constella here and they are same family of drugs...so many people on this site recommend magnesium but I have an arrythmia and long term mag use not a good idea for me. My problem became significantly worse after beginning Prolia injections for osteoporosis. Sorry not a big help, but try the senokot occasionally and see.

Sweet potatoes, avocados, garbanzo beans, spinach, bell peppers, artichoke hearts, pears, raspberries, strawberries, chia seeds...and Beano if you don't eat these yt.
