I'm on 1500mg per day (2x850mg), have been for the past year and I've had amazing results. I was prescribed met years ago but never took it because my doctors failed to explain to me just how much it might help me. They kept telling me it's to lose weight.
I've had great results as far as weight loss and restoration of my cycle is concerned. I've lost 85 lbs since May last year and my cycles are fully restored including ovulation.

Needless to say, I'm very happy with it.
