Had to have a barium enema a few years back & was given picolax to take the day before, whilst only being allowed clear fluids such as black coffee, black tea or bovril, went for the bovril option & without fail 60 seconds after drinking the bovril I was shitting it out totally un affected by my digestive tract. My best advice is lock yourself in the toilet for the day & don't let anyone tempt you away from it or a nasty case of brown trousers may result.
Hope everything is ok by the way & keep smiling.
