Very interesting. Maybe something in your healthy diet is causing constipation? I just learned I have been using way too much pea protein powder isolate. I cut it back for an unrelated reason and voila - no constipation! Separately, my adult child did a gluten challenge test and ate wheat products instead of gluten-free substitutes. He was less constipated during this time, surmising that the gum (or rice flour) in the gluten-free products was the culprit.

That is why, IMO, it is SO important to experiment with diet in treating constipation; you may not need OTC or prescription drugs. If you can find a food solution, I just believe it is better for your "whole health."
