Failed prep for colonoscopy: What can I do?

good evening, I am a 58 yr old female and I have had colonoscopies every five years since I was 22yrs old, had IBS at that time and Polyps. I have had polyps every time so I repeat my colonoscopy at five year intervals.. I have tried so many preps and they make me so sick to my stomach that I have had to get something for nausea just to do a bowel prep..... Just 3 weeks ago I did HAPPY COLON FOODS prep kit and it had breakfast,lunch,dinner and 3 small snacks so I actually to go eat all day, wasn't a large amount , but more than enough to keep me from getting hungry or nauseated. I took a dose of this tasteless powder in a bottled water and a tablet, Every time I ate and had a snack. ALL of that was included in my kit for 45.00 plus tax and shipping. Very detailed instructions. I had no cramping, no nausea and no bloating. BEST ever, I would recommend this prep to anyone, especially people who have problems going without food, even a diabetic could to this prep. I see the GI doctor that invented this prep, Dr Jeff Scott in Oklahoma City, and I think his prep was a great invention and well past due for the GI community!!! They have a helpful website also. happycolonfoods.com I ordered kit online and got it in 2days.

My fistula connected the ileum of the small intestine to the vagina. I was diagnosed with Crohn's at that time. Do to the fact that there were numerous ulcers from Crohn's, they performed an ileostomy to allow healing by use of a biologic(Stelara). 2 &a half years later I had a reversal.

This was the easiest I've ever done and I've done at least 5 in my lifetime. Nothing can be simpler than taking pills and drinking water.

@catherine1290 It's been over a year and I have not had reversal surgery yet.
How was it after waiting 2.5 years?

My colonoscopy failed last October so I got another one this month and I was clean.
I started taking 1 capful of Miralax every morning a week before. I started eating all junk food and cut out the fiber.
2 days before start a clear liquid diet only. At 3 pm put 64 oz of Powerade into a pitcher and add 255 grams of Miralax. At 5 pm start drinking 6-8oz every 20 minutes until gone. Clear liquids only that night. 1 day before procedure mix the 1 gallon of nulytely and refrigerate. At 4pm start drinking it 8-10oz every 10-15 minutes until 1/2 of it is gone. At 7 pm take 2 ducolax tablets. Clear liquids only the rest of the night. 4 hours before your procedure drink the 1/2 gallon until gone. Don’t eat anything and no drinks 2 hours before your appointment. I was clean after doing this 2 day clean out. I was starving for food. Good luck!
