how long does it take metformin to kick in
Any one who's gone off Metformin . . . how long does it stay in your system?? I know it takes 2 - 3 weeks to kick in when you start taking it, how long does it take to completely leave your system when you stop? Due to my increase in exercise and lowering of carbs I have stopped taking it (2nd day) but feel that kind of weird lowish, head spinny thing.
