My one experience of a colonoscopy was as a private patient (I was still married at the time and my husband had private health insurance through work). The "prep" was done 30 minutes before the procedure. The nurse inserted some kind of pessary and told me to hang on as long as possible before going to the loo - I lasted about 45 seconds before having to dash in there. Sorry to gross people out, but this method certainly cleared everything out, and shortly after that I had the actual colonoscopy. So what I'm wondering is why the NHS makes people go through unpleasant long-winded preparation with slow-acting laxatives etc, when there is a much more effective and efficient drug that could be used? Presumably it comes down to cost.
Hope you can find a good solution Newbs, it's not a pleasant procedure to look forward to. xx
