Polyethylene glycol 3350 with electrolytes
"Had to take before my colonoscopy, and really had trouble keeping it down. I gagged and threw up more than I got down (or so it seemed), but it did begin to clean me out. Almost through the first course (started at 7:45pm and it's now 9:40pm), and I'm already dreading the second round that begins at 2:00am for my 7:15am appointment. Not looking forward to this again. Will ask for something different the next time. I would forego the colonoscopy just so I could skip the prep, but with pre-cancerous polips found three times in the past I can't skip having my yearly colonoscopy. God help me!"
