I thought this book was fantastic:
Amazon.com: A Patient's Guide to PCOS: Understanding--and Reversing--Polycystic Ovary Syndrome: Walter Futterweit M.D.: Books It explains how PCOS affects our whole bodies, not just our reproductive abilities. It can be a little academic at times, but just re-read when you need to or put it down for a bit if it starts making your eyes cross and your head swim
As for changing your eating habits (I assume that's part of what you meant), this book has some good info in it:
Amazon.com: New Glucose Revolution Guide to Living Well with PCOS: Dr. Dr. Jennie Brand-Miller M.D. M.D., Dr. Nadir R. Farid Dr., Kate Marsh: Books
Best of luck to you! I know it can be overwhelming at first, but PCOS is very manageable with the right information.
