I just did the Prepopik prep and hated it. It is a split dose. You drink 5 oz of the prep followed by 5 glasses of any clear liquid over a 5 hour period. Then, depending on the time of your colonoscopy, you do it again around 6-8 hours later. The advantage is you drink such a tiny amount of icky tasting prep. It just didn't work that well for me. I was on clear liquids all day, then started the prep at 6:00 PM. It took me until 3:00 AM until I had my first bowel movement, and I was bloated and in pain until then. I prefer the old preps...even though you need to drink more horrible stuff, it works faster and wasn't as painful for me. My doc says most people love it though...I tend toward constipation, so maybe that's why I had a tough time with it.
Wiccan-chik....good luck with the colonoscopy..I hope you get good results!!
