you really should re-read the book. it is very important to drink a lot of water....generally one should drink about half of their body weight in ounces of water. so if you weigh 200 lbs, you should drink 100 ounces of water each day in addition to the 6 - 8 glasses of lemonade, the quart of the swf and the lax tea.
here is a link to the book...it's short, but extremely informative. good luck to you!!
