polycystic ovary syndrome
"I am currently on Metformin for PCOS symptoms. However, blood test after blood test has shown that I do not have PCOS. I have all the symptoms and Metformin is working to regulate my cycles. The only downside is the weakness, light-headedness, and sleepiness I am experiencing. I have read that it is possibly from lactic acidosis, which is frightening. I am increasing my water intake and exercise and hoping that it will go away."
