What a fantastic book! I am 43 and, based on what others have told me about what's to come, was terrified of perimenopause. This book is a wonderful and affirming reference that I would recommend for all women, no matter what the age. Dr. Gunter is an OB-GYN with a no-nonsense, science-based approach to the issues and mythology surrounding menopause. Her mantra seems to be 'this works for some, not for others, here's what the science says' which empowers you to make best decisions for you. It has definitely given many talking points to take to my practitioner. There are chapters on hormones, supplements, and birth control as well as the symptoms and physiology of the perimenopausal period. I love that she discusses hormones as a valid form of therapy and/or birth control without the shaming and fear that accompanies some of the other texts I've read (I'm looking at you Lara Briden). I will probably end up buying a physical copy of the book as well for easy future reference. The author is the narrator and she does a great job with that as well.
