Hello, ladies. I, too, have PCOS (diagnosed in Dec. 2008) and have found a lot of help in the combo of LC'ing and Metformin. Yes, it did cause me (A LOT of ) stomach trouble at first, but it really tapered off after a couple of months. Hang in there! Oh, cinnamon did help the side effects some...so did ginger. It really did well for me.
