You have obviously never had a colonoscopy. Billy C describes so accuratelyI was on business in Dubai a few years ago and decided I needed to get some Lomotil urgently. Went to a pharmacy in a mall and the pharmacist told me there was no Lomotil left in the Emirates so he gave me something called Motilium. Although I was suspicious of the name I took a couple and within five minutes was sprinting for the toilets, where I had to go every ten minutes from then on. It took me two hours to get away from the mall to my hotel room where I Googled Motilium and found that it is a drug used to enhance bowel activity. Bastard pharmacist.
