at the end of 2008 I took a fiber supplement called colon pure and in about 3 months Jan-09 I lost 10 pounds, all on my stomach area, I ended up with a flat stomach. After this incident I suffered a lot of gas, nausea , stomach pain, cramping and very thin stool. Now 2 years later my stomach is protruding like I m pregnant and almost always in pain with the cramping and gas.
