Wow girl, you've already lost 30 some lbs? Remember how much you've lost! I know, it's discouraging. I have PCOS and Insulin resistance and believe me, my *** has to be eating next to nothing to lose any weight. I feel ya!
Metformin actually helps promote weight loss. The best thing I have ever been on was Byetta for type 2 diabetics. I lost 20lbs in six months without changing anything just because my body wasn't effing around with insulin.
