Creondave,
I like to use activated charcoal with plenty of water to push it through my gut.
Also, I don't know the exact name, but I call it the doggie pose: get on hands and knees, lower your head and 1. Rock back and forth 2. Same position but lower the whole body, arms outstretched. How can gas/air be so painful?? ShelleyW

I’ll be following what your doctor advises since I seem to be having the same issue. Was doing fine with Miralax and Metamucil for almost a year, and suddenly the flatulence came on with no change in diet or lifestyle. It’s frustrating.

Chew two Beano tablets before eating meals or large snacks. Helped my husband tremendously. He never goes anywhere now without the Beano.
