If you google metformin and PCOS you will get some good information come up there. The first link is one that I have referred to quite a lot for a good, simple explanation of what PCOS is and how it is treated and managed.

The other thing we did was the CSIRO eating plan... we haven't stuck with it too rigorously, but I did lose 4kg reasonably quickly by following those guidelines. I'd still like to lose another 4kg, but at this point I'm no longer in an overweight category according to my BMI so I'm pretty happy.
