Hi
Just looking at the forum. I have been on metformin 500mg, 1 per day for about 2 years now. When I first stated taking them, I had the usual side effects of stomach cramps etc. I asked my GP for the slow release tablets (SR), which I tried and al the side effects disappeared. I know I'm only on 1 tablet a day but it did work for me. I assume the Slow release metformin tablets are more expensive than the normal ones, hence they weren't prescribed initially, but if you're not already on the SR ones, insist that you go on them. Best of luck
