Tried it a couple of years ago and they found blood . I was given a time to go to the North Tees hospital . A liquid to drink the day before starting at 4pm . Never been to the loo so many times in a month . I thought one could flush and that was it . Not with this stuff . After many many times its as clear as water . I was afraid to go to sleep that night in case , but was OK . At hospital down in the cellers ( thats what it felt like ) many mini rooms to check people out . I was given a gown and paper pants sent in to a mini room to face 5 very pretty women they laid me on the bed injected something in my arm and I was sleepy and not aware of what they did . But they pump air up your rear to streach it , then inspect . I came around on they said right you are all clear go and lye down on a bed in the ward have a drink and a snack . What they dont tell you . Is the air they pump in must come out it did, a school boy in class would have had a record for that noise and lasting time too. My wife drove me home and I farted constantly . The only down side was the paper pants had been torn off me by these very pretty nurses AND I CAN'T REMEMBER A THING. Last time they sent the card out for more it was all clear again.
That's for colonoscopy (camera); for virtual colonoscopy (CT scan) they pump you with co2 and you
think you want to fart but don't, it's all absorbed by the body
