For years I have been told I was boarder line diabetic then last year I was told I have type 2 diabetic and prescribed Metformin. The reaction I had to Metformin cost my wife and I £2,100 in new carpets and furniture. I then cut out all sugar and bought a glucose monitor which showed on average my blood glucose was 7-10 mm/l. Now for the last 4 weeks my monitors shows I have a blood glucose of 20-30 mm/l. I have absolutely no symptoms at all, not even wanting to pee or drink. I have bought a second glucose monitor which tells me the same 20-30 mm/l. Any suggestions as to why.
