Low blood sugar?: Hold the metformin till you contact your doctor as your blood sugar may be getting too low. Do you have a home glucometer to check your blood sugar?

Hypoglycemia, to the extent where you get lightheadedness is not often associated with Metformin, however it would be prudent to check in with your PCP. Metformin is a drug to control your insulin regulation; should not be confused with a weight loss drug. There is unfortunately no substitute for diet and exercise, which will BOTH help with PCOS as well.
