hi guys.im over in scotland,uk and ive had a few colonoscopys and theyre a breeze,i usualy just go for the sedatition and its over b4 you know it then its a sandwich and a cuppa.i get stuff called picolax which is only 1 small glass about the amout of a can of coke or pepsi and it cleans you out just as good as the 3 litres of stuff ive been made to take,any time i have a test i opt for the picolax,not sure what you guys get but theres always another option if you dont like the vile stuff they offer you first,
