I took freeze dried breast milk for my SIBO, then added goat milk yogurt, seemed to help a ton...cut out the PPIs, but the docs want me to get back on the PPIs, so I'm struggling with the tossup, acid reflux, beat up esophogus, or laying in bed in pain with a hot pad. I too, "microdose" the psilium fiber, cause too much, is too much, and it's easy to get too much! actually little fiber gummies seem to be just about the right amount for me.
