I think my metformin was doing me in. I've been feeling under the weather. Its contraindicated with one of my other meds (topamax) - i think this is why i stopped taking it before when i was taking it, several years ago. I didnt take it yesterday, after decreasing it from 1000 mg to 500 for a couple of days, and im already feeling much better. Like im waking up and feeling ALIVE, like a new woman!
