Hi, I started taking this tablet 5 days ago, and I have already lost 4lb, not sure if that amount of weight loss in the beginning is normal or not? I am 27, was diagnosed with PCOS when I was 15 only have like 4 periods a year if im lucky, so was put on it to make me more regular, I don't ever feel hungry sometimes feel quite sick and the thought of food makes me feel ill sometimes so don't know if that's the cause of the weight loss,

Has anyone else been on this type of Metformin who could give some advice?
