A Nurse Practitioner who worked on pelvic floor disorders guided me in controlling this problem, though I was not post surgery like you @andoman. I tried different fibers first that didn’t work. But Benefiber works like a miracle for me. Even their gummies work instantly. My primary care doctor told me her patients were telling her they didn’t work and I have to wonder if it is just individual differences or were they taking them for constipation?
