polycystic ovary syndrome
"I was misdiagnosed with depression/anxiety.  Stopped menstruating in 2000 after taking the birth control shot. Gained 80lbs I can't shed.  Started taking metformin after doctor connected the symptoms I had with my 4 miscarriages, and that I had to take fertility drugs to have the 2 children I have. I felt immediately better. Still have a hard time trying to shed the weight, but I feel like awful when I don't take this medicine."
