What a story. I have learned a long time ago that up to a point doctors are very knowledgeable, but we know our bodies better then anybody else. With all the advances of modern day medicine, in so many cases often times it comes down to trial and error. Like I said in my previous post, because I don't take Metformin, I don't have any personal experiences that I could share with you, but if you ever want to discuss issues related to diabetes, please feel free to ask. If you haven't seen this web site, I suggest you take a look at it.
