Query: Very Exciting!

I just finished phase one. The first day was the hardest and I had horrible migranes but every day after my energy levels were through the roof! My skin is clearer and softer and I'm not tired! Oh, and total, I have lost 8 lbs! 4 were water weight but I lost 4 during phase 1 and an inch off my waist. I don't normally do diets because they are unhealthy, but this system isn't like most diets because you can eat a lot of food and you don't have to worry about counting calories cause you are eating all healthy foods. There really isn't much reading to this book which I like as well. It's short, simple, inexpensive and to the point.
