UPDATE......I was diagnosed with PCOS on August 13th. I began Metformin on the 14th. I have had no real problems with this medicine at all. Can tell a difference in stools. But no sickness. I actually feel like I sleep better. I don't feel as bloated as I used too everydday. BUT I have not lost any weight......however I do feel like my appetite is changing, like I don't crave food like I did before (could be from medicine). Not discouraged yet as I do feel like I have more energy.......we'll see how the next couple weeks go. I will keep posting
