In May of 2010 I was diagnosed with PCOS. in my case their was nothing wrong with my ovaries but I did have insulin resistance which caused me very bad acne, no period at all, alittle facial hair, and definitely darking folds around my neck and arms.My OB/GYN put me on metformin and birth control. A year later I've lost 61 pounds because of it..i feel amazing. It was slow in the beginning because of the side effects from the metformin ex. stomach bloat, gas, diarrhea, and ingestion.
