Metformin makes me ill, only taking one 500mg SR tablet afternoon, it slows me up, headache, pains in back and chest, feel sicky, horrible but my dr asked me to try carry on & stop for short periods if need be.
I also take gliclazide morning & evenings but the metforminin does give me better bs control.
I also hate taking it as i do the statins which give me wrist pains.
