Hi: I gave up on many docs who said Miralax (gave me incontinence) and 64 oz of water. Got tired of "fiber". I got Linzess which worked for me except I had terrible achyness all over and I have rheum. arthritis and had to quit it. Maybe the side effects are why other docs didn't give it to you. Try it. It might just work for you and anything helps to defeat constipation.
