bowel preparation
"can I just say, these horror stories got me so worked up I was dreading this prep, the reality is its NOT THAT BAD!!!. Ok so the drink isn't great, like a salty lemonade ( I find the cranberry powder things disgusting too but if I've got a water infections I drink it!).

I found the 1st litre easier to drink than the 2nd,with the 1st one I used a whisky size tumbler and drank it through a straw at room temperature. I drank it all within half an hour and it started working within the hour. The 2nd litre took longer,I used a bigger glass and filled it with ice, I found it harder to drink cold and the larger glass never seemed to empty so you feel like your going forever! 

Don't be put off by the scary stories!"
