So I did everything correct for the colonoscopy prep but only a bit of diarrhoea. Took it over 4 hours ago and only been 3 times . Drinking loads of water and a coffee with help? It’s still murky looking . I have to ensure it’s clear . I don’t want to wait any longer for this procedure to find out if I have cancer but I know they may cancel if my diarrhoea is not clear . More prep to take in the morning . Should I be clear tonight though ?
