Great advice. Easily understood.
A wealth of information back by science. No mumbo jumbo. No product to sell (beyond the book). This book offers answers with scientific reasons to back it up. If I don't change my review then please feel free to assume that it worked for me.
NOTE: Please heed the warnings to see your doctor if on medication. Your doctor should be your partner in this. Mine recommend this book. And he is a no nonsense kind when it comes to medical science (nice chap too).
