Kudos to Kathryn Petras for writing a book on a subject that is long overdue. This book holds a wealth of information pertaining to menopause which has, until now, been unobtainable. I'm 48, not necessarily Pre-Menopausal, but have been suffering from many of the symptoms Kathryn describes. My plan is to be tested, ASAP, in order to begin preventive treatment. This book was fantastic and I am rushing a copy to my girlfriend in Westchester who may have been suffering of premature menopause for years. The doctors do not take her seriously. At any rate, BUY THIS BOOK. Finally, the truth about menopause has been revealed as well as many ways to treat and/or deal with it. THANK YOU, KATHRYN PETRAS!!!
