Hi Liza, I'm afraid the weeing is all part of the Cambridge diet and it doesn't stop. Basicly if you drink it, it has to come out. You really must keep up the drinking though as our bodies would usually get quite alot of water from the food we eat so when we eat less we need to drink extra water. Drink at least 2.25litres (4 pints). As you get further in it gets easier to drink more. Good luck and happy peeing lol xx
