Ive been diagnosed and I started metformin in February. Before then I was eating high amounts of sugar because my
Body never absorbed what sugar I had eaten. Since then ive done from morbidly obese to lower obese BMI and partly it's due to metformin. If you are overweight and find it difficult to lose weight it is a really good option in my opinion. It's also helped regulate my periods which before had been sporadic at best.
pM if you want anymore info :)
