For years I dealt with severe depression, painful digestive disorders, bronchitis, and recurrent yeast and bladder infections. Less than two years ago I bought this book as a last resort. I didn't know what to expect if I followed its recommendations - I was desperate. To my great surprise, it worked! I am presently free of all the above symptoms plus a host of others too numerous to mention here. Yeast may not be your problem, but it sure doesn't hurt to find out. It's definitely worth the few dollars for this book. Because of the dedication and open-mindedness of its author, I am healthy and truly happy for the first time in my life. I wrote him a thank-you letter to that effect, and he replied with a handwritten note of congratulation and urged me to spread the word about this illness. Buy this book - you'll be glad you did. I am.
