I am a 51 yr. old cervical cancer survivor w/chronic gas/diarrhea, & a hemmaroid. When I started my prep, my hemmaroid started bleeding immediately, & my behind got so raw so fast from the diarrhea, I had to stop the prep & cancel the procedure.
Oh; Laurie! 
Was someone at home with you? (I hope so...)
Perhaps a gentler type of prep would be better in your situation, but if you haven't already healed enough to consider even that option, maybe a virtual colonoscopy would be a good substitute for the "real" thing in the interim. Biopsies can't be taken, but at least a thorough "look-see" can be accomplished.
Thanks for writing.
My best,
Hope
You're welcome, Laurie.
You didn't mention which prep you used, but I can tell you that LoSo prep (active ingredients: bisacodyl and magnesium citrate) does a good "clean out," is well tolerated, and is considered gentler and easier to use, by many people who have tried other frequently recommended bowel preps.
Virtual colonoscopy Virtual Colonoscopy is a fairly new method that uses a CT scanner and computer virtual reality software to look inside the lower digestive tract without having to insert an endoscope. (A thin catheter is inserted into the rectum, so that air can be passed, to temporarily inflate the colon for better viewing.) Some prepping the day before is still necessary, but overall, the procedure is much less physically and emotionally stressful than a conventional colonoscopy. However, remember that tissue samples can not be gotten, so, if suspicious growths are seen, a conventional scope will be likely.

Uh, get a grip ladies, this prep takes only a day or two out of your life, and the procedure itself isn't all that much, so just do what the instructions say, stop sniveling, and prepare to have a procedure done which could very well save your life.
I had it done 3 years ago, without anesthesia (some hospitals put you out) and it was really no big thing.
We're so spoiled in this country, we'll only eat and drink things that "taste" good, and most of us eat a very limited range of foods, usually loaded with sugar, salt or fat, and we turn up our noses at anything different.....this is why we suffer bowel disorders in the first place. Ever eaten a turnip? Rudabega? Bok choy? Endive? Beet? See.....you're ignorant and spoiled, and you should get smart, do the prep, take the test, and then revise your eating habits.
Judi, what's up the with the flaming?
Ouch!
Hope
PS: I'm vegan AND, I have a post graduate degree in Health Education. Not only have I tasted turnip, rudabega, bok choy, endive, and beets, but I can probably put together a succinct, 45 minute presentation about their various health benefits, on the fly. I'm not ignorant (though, I will admit, having tasted those five veggies, I don't like any of them). And, I neither are our community members.
Judi,
We're all allowed our opinons but I must object to your tone and negativity. From your post I also can't imagine that you have IBD. for many of us with IBD or other gut issues it's not the taste of the prep that's the issue it's what's IN the prep that causes problems.
A colonoscopy sets me back at least 1 week, usually 2-3 weeks, every time I have one done. Why? Because it causes my IBD to flare-up. I can easily lose 5-10 pounds in that time - not good since I fight to maintain a weight of 115 lbs. due to the IBD - and can have other serious complications from the prep as well.
This site is not only a place to ask questions, to get answers, and to give opinion. It's a place to share feelings, frustrations, and sometimes even anger about living with a chronic illness for which there is no cure.
Glad that the prep is not a problem for you. But for those of us who do have difficulty you're just being plain mean.
Read my shareposts and you'll see that I've changed my life, my diet, and my career hugely to live a good life despite having IBD. I eat only a whole food diet that I prepare myself. So, please, don't lecture until you get to know each of us intimately.
Thanks, Judi. I appreciate your post and all that you, too, have been through because of IBD.
I agree that there are many people who simply refuse to accept the idea that a poor diet, or even certain foods, could be exaccerbating their IBD. But, most doctors don't accept this fact so how can we expect IBD patients too?
With my blogs and my book - Living with IBD & IBS - I try to educate other IBDers about nutrition and stress reduction to help manage their symptoms. These things won't cure most of us but they have both been unbelievably helpful to me.
Glad to have you aboard.

Oh boy, aren't we excited about this! I had my 1st colonoscopy 3 weeks ago. The prep was EXTREMELY difficult! I think it was probably due to the fact that I was already severely dehydrated (from severe diarrhea) and nauseous. Basicly, I did not need a lot of prep because I had already been cleaned out for quite a while. When I called my Dr.'s nurse (in tears by this point I will admit) to ask if I could just drink part of the prep she said "absolutely not! if you don't drink it all the doctor will not do the procedure." The next day when I got there I told them that I drank 75% of the stuff (I lied a little- I only did about 50%). A different nurse told me that they never expect patients to drink it all. I was so ticked! lol. Next time I think it won't be as bad thanks to some of your tips & others that I have read after the fact. Thanks for the advice!
