I can't take metformin and my doc just has no clue. What can I do to help with the pain, horrendous mood swings, acne, and all the rest of the symptoms with pcos. I'm desperate to have something change I truly can't keep living like this. The mood swings are so bad for me and my depression is getting worse. I do really good with diet and exercise but I'm still struggling with my weight and getting it off and keeping it off.
