If you think you are going crazy, you are not. You feel rundown, you are not interested in sex, you need more sleep, your mind handles information like an Intel 80386. This book is the answer. I have bought copies for my family and friends. I have recommended it to my business school class, and the MEN referred it to other women they know. Vliet gave me the ammunition to say, "No, it's not just that I'm getting older, and it's not just that I have young children, it's that something is wrong." I had my hormones tested, and despite lab results showing them to be "normal," they were all BELOW NORMAL for optimal function according to Vliet's clinical experience. This book is the best money you can spend on women's health. A literal lifesaver.
