Query: LIFE SAVING BOOK

I've been ill all my life with asthma, sinusitis and eczema and five months ago quit my job because I was too sick to work. After 10 days on the diet my blood pressure has gone down, I'm losing weight and the 1st reason for reading it, I have lost 95% of my asthma and sinustis symptoms. I know I'm finally getting healthy and with far less money than I use to spend on doctors and perscriptions. I recommend this book to anyone that wants to get healthy again.
