Hi MedicalUnicorn,
Could you have a redundant colon? That could either be a contributory source or "the" source of constipation. A gastro MD should see a redundant colon during a colonoscopy. There are ways to eat to reduce its constipating impact. Sometimes gas gets trapped too. Certain floor stretches and just walking can iron that out.
If not that, as miralax/metamusil and such do not work for me (I have a severely redundant colon), I rely on slippery elm powder (inner bark), magnesium citrate, kiwi, rhubarb, spinach, chia powder (or seed), cooked vegetables, food-source fiber with every meal and avoiding whatever foods seem to constipate me, as well as Colace stool softener as needed . Water, of course, as it seems to absorb into my body more slowly than other drinks. Exercise, stretching. Stimulant laxatives work, but are harsh. Someday I may need them though.
Keep trying things new things. Anxiety and stress should not be ignored either.

I agree with the no fiber approach. Only made me worse too!
When things are real tough for me, I make what I call my prune juice cocktail which includes prune juice mixed with Milk or Magnesia. Several nights a week I take 2 stool softeners with a glass of prune juice.
Also, my gastro doc prescribes Trulance for me. This Rx med is powerful!
