I am so frustrated. I've been on 500 mg of Metformin HCL twice daily for PCOS for a week now. My doctor didn't officially diagnose me with PCOS though. She said I'd need a pelvic exam. I have the symptoms of PCOS though so she prescribed me Metformin and then sent me for bloodwork (which was normal and said she didn't need to see me again...which doesn't seem right to me). Anyway, at first the metformin was making me sick and tired. Now I'm not sick or tired but STARVING. I'm constantly starving and it's beginning to infuriate me. My internet searches show that this isn't normal. I don't know what to do and this isn't acceptable. I can't constantly eat. Can anyone help me?
