Try taking fish oil capsules. They’re good for everything. I’ve taken them for 13 yrs 5x1000’s it was taken for cholesterol and it has been terrific. Olive oil. Fish oil at Costco 300x1000 $10. Apples. Oatmeal is my go to. I make special oatmeal. Use really coarse ground thick oats. Little milk and brown sugar. Don’t get stuff in envelopes. your dr should be helping you with something daily. But try to find some food item or type with lots of fiber. Anything that gives you diarrhea will work. Then diet might be more helpful. Small bottle of magnesium citrate will send you to your porcelain throne fairly quickly. They used to use it for barium tests. Good luck and I hope everything comes out in the end!
