I Am Preparing For A Colonoscopy On Mon. I Had

I am preparing for a colonoscopy on mon. I had a whipple surgery 3 years ago and I am taking zen pep to aid in digestion. I had a colonoscopy 4 months ago and was not completely cleaned out so doctor ordered a follow up test. I have been taking zen pep to aid in digestion. Usually I have no problems with constipation, just the opposite. I started a 2 day prep yesterday and have not had a bowel movement yet. I have been on zen pep 22,000 one with every meal. when I started drinking only liquids only, I continued my zen pep with broth or what time I would ordinarally take them about 3 times a day. Would the zen pep stop the cleansing process? I also have type II diabeticis. Lately my gluouse reading is elevated. Does that make your readings increase?
