  • The Yeast Infection No More book has literally saved my life. After years of getting no help from the established "medical profession" and getting sicker and afflicted by pain mood swings and depression, I bought your book and in less than5 weeks my chronic muscle aches and joint pain, caused by my candida yeast infection, have disappeared, and I literally tossed away my cane that I have been using for years. I couldn't believe it, it was nothing short of a miracle. I still can't believe it. Now, months later, the depression has also vanished. I no longer cry with no reason and I feel happier and energized. I am sure the protocols in your book have saved untold thousands of people like me from suffering and pain and "given us our lives back." I will never understand why don�t doctors tell us or investigate more on the subject of candidiasis. Two of my friends, one of them a naturopath had recommended that I try your program. And just like that, I was cured and liberated from years of misery. I have recommended your book to numerous people and all have received a great deal of relief. If only I had been told about it sooner, it would have saved me years of pain and exhaustion. I really tried everything. After 2 months on your program, people say that I look10 years younger, and they are right! Thank you very much for everything you have done for me! ➤➤
