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.
Re: How long does it take for synthroid to kick in? The doctors say it takes 3 weeks to start to notice a difference. They won't check your thyroid blood work until you've been on a dose for a minimum of 6 weeks. This is how long it takes to get into the part of your blood they use for the tests. When I started medication I noticed a big difference the first day, and was improved for the next 2 weeks.
