This may or may not be of any help to you, but I started Met in July 2007. I didn't notice a change, but we went straight to IVF. That failed and I got pregnant the following month (October) on Metformin alone. I was also on 1500mg/day. So it CAN work in 3 months...it did for me. But I don't know if that's the norm or if I just got lucky as hell.
