bowel preparation
"This is the worst thing I have ever tasted in my entire life, I took me ages to drink the first litre, after I felt sick, stomach cramps then 2 hours after drinking the first litre the heavens opened! I tried to drink my second litre but I physically couldn't, I drank 500ml of it and I threw up the whole river nile (after drinking 1l of water inbetween). Worst experience ever! And I'm starving LOL"
