In my family we call them barn burners! I am sans gallbladder and 18" at my TI. The D was like acid on me. Ow, Ow , Ow was all I said with every trip to the potty. I had tried the psyllium powder but it was still too much fibre for me - I think that was the issue.
I had been on cholestyramine many years ago and mentioned it to my new GI. He immediately put me on it and I am finally not feeling acid burns any more. I also found that greenish hue is gone (well unless I am bad and eat something I shouldn't that's green!)
