I'm having my first fasting blood test tomorrow, three months after starting Metformin. But the thing is, isn't it dangerous to fast AND take Metformin? The drug is supposed to lower the blood sugar but if you don't eat, won't it get dangerously low in those 12 hours of no food?
 
Doctors will tell you it is impossible to hypo (get low blood glucose) when on metformin.

There are a couple of people who post on this forum who have experienced hypos when on metformin. But I think it is very rare.

Do you know what your usual blood glucose levels are?
