Polyethylene glycol 3350 with electrolytes
"I'm about to do this colon cleansing for the 3rd time for a colonoscopy. The first time I added the flavor packet, and OMG, the taste was disgusting. The 2nd time, on advice of my sister, I added no flavor packet. It was still disgusting, but a lot more palatable for me. However, the 2nd time didn't "clean" my colon completely.



It smells and tastes like it's something you'd use for car repairs. That's how bad it is. After the 1st gallon, it starts to get harder to drink every 15 min. and keep it down and not vomit it up.



Another doctor prescribed a colon cleanse for a hysterectomy consisting of 2 7 ounce jars of Miralax in a gallon of water. I found it a lot more effective and more manageable."
