Yes it does say that in the book. It says that extra water may be taken as desired. It also says 6 to 12 glasses of the lemonade daily during the waking period. So basically you drink the lemonade and nothing else unless you get really thirsty. It also says to drink another glass of lemonade if hungry.
I had to re-read that myself.
I ended up using more of the lemons and cayenne pepper this time because I felt that I needed a better detoxing. Well because I was drinking 9 glasses of water a day (half my body weight in ounces) I was litterally washing it out of me. No wonder. lol
I'll go back to my normal amounts then and less of the water.
