I'm in the same boat, i'm thinking intestinal inflammation for me. The IF1 doesn't do anything anymore. I haven't had a solid bowel movement in weeks, just water, and i'm holding lots of water in my gut now. Not even sure what to do so i'll follow your post see if you find an answer.
I tried taking castor oil to see if there was blockage, i've done coffee enemas, liver flushes, garlic enema, acv enema, colonic, tried the pumpkin/wheatgerm/molasses concoction for tapeworms, nothing.
