... and on taking metformin. I have been taking it steady for a few months now and am not loosing weight at all... unlike the first time I took it. Why is it that I am no longer loosing weight and is this a normal occurrence? Has anyone else noticed this? I would like to mention I first took it in 2005 and lost a considerable amount of weight. I got pregnant and had my 4th and last child in 2006 gaining a good bit of weight. I have been on and off metformin every since and I have not lost any weight at all
