Polyethylene glycol 3350 with electrolytes
"This is only my second colonoscopy, ( I am 60 yrs. young) My doc gave me the Gavilyte-N. It was not too bad as I made it this morning and let it chill. The first few glasses went down ok. But I am down to about 2-3 more glasses away from being finished tonight. I have had the worst nausea, gagging, and near vomiting I have felt in my entire life. I hope to God I never have to do this again. There's no history of polyps or cancer in my family. Calling it done once this procedure is over."
