Polyethylene glycol 3350 with electrolytes
"I have my colonoscopy tomorrow - started my prep at 7, got all the medicine down like instructed. Literally 10 minutes after the first liter, I was on the toilet. To be honest, haven't really left yet. Just about to start 2nd liter and wondering how I will do it. I don't see myself honestly getting it all down - but I do know once I start to run "clear" I am quitting. I'm going diarrhea to severe constipation. I can't seem to get my bowels on track and haven't for 2 months now. Only 35, so hoping it's just diet related. Good luck to anyone in my shoes."
