Was diagnosed 2 years ago with HBA1C of 100 went on 2 metformin a day then after first 3 months HBA1C was 37 then 38 so was took off medication for 9 months readings were 48, 51 then 80 so went back on metformin but 4 tablets a day. New reading is 42. I am constantly been told am a bit of a mystery and that I shouldn’t get those readings on metformin alone. Had two thyroid tests all ok. I am convinced there is something else going on instead of diabetes. Quite sick of hearing they don’t know what is going on with me. Finger tests are always so erratic. Any thoughts anyone.
