I remember that in the book it said, and I did this, that if you get lightheaded and tired from loosing too fast that you can try adding an ounce of nuts or seeds. It worked for me and I think that I was about 7 days into it too. Hope that helps. I can't remember if I did peanuts or sunflower seeds, but I do recall it worked and I actually remember feeling the results rather quickly too. Dr. A said that there is no reason for you to have to feel washed out if even for a day. Good luck. Annie
