This Plan has worked for thousands of people, say the authors. I started on it 07/05/98. As of 07/27/98, I have lost 11.5 pounds. I feel great, my skin has cleared up, I no longer have indigestion or heartburn or gas. My blood pressure is back in the normal range. My hair is thicker and I no longer find hair in the bathtub drain. My energy level is very high. This Plan WORKS!
