Hi, I just joined this board but I have been Diagnosed with PCOS since 2000. I am on Met. While it's often helpful in losing weight that is really not what it is made for. If the only reason your Dr. is giving for your dosage is your weight, you may need to find a new Dr. And, if your Dr. told you that she/he was putting you on Met to lose weight and not saying anything about controlling your insulin. Again see a new Dr. because there are much easier ways to lose weight then taking meds. But, I don't think that just because you are not losing weight anymore that it is the wrong dose.
