I took Met (1500mg extended release) for years, and didn't see any weight loss other than the five pounds caused by dehydration at the beginning. When I took Met and ate carbs together, I would have the worst gastro issues! Over months it became obvious to me, every time I ate carbs, I was sick for the next 24 hours. The doctors didn't believe me, but I stopped taking it for that very reason.

Met also didn't keep me from gaining weight, didn't help reduce the amount of body hair, and didn't regulate my periods. I also had just as many migraines as before taking it. The main reason I stopped was the gastro issue.

It didn't make sense to pay for a medication that didn't do a darn thing for me, and in fact, made me more uncomfortable than going without.
