Bowel Preparation
"I was prescribed this by my dr. for a colonoscopy and I&#039;d say it started working in about 30 minutes.  Unlike others, I had no problem drinking it as my dr. advised me to mix it with orange gatorade.  I mixed it early in the morning and refrigerated it until about 5 pm and was able to chug it down.  For me it was easy to drink because it was cold and the gatorade made it sweeter."
