Hello all, This may seem like a very innocent question .......but is there such a thing as a normal dosage of Metformin? I suppose I am needing to know what the maximum is before insulin is the next option. I was diagnosed as Type 2 at the start of this year and was prescribed 2000mg Metformin daily......building up over a few weeks from 1000mg to 1500mg and now 2000mg. My Doctor does not think that diet alone would do the trick. I realise that we are all different - but I'd like to know if others would consider this a high dosage. Many thanks.
