I was diagnosed on May 30th with an Hba1c reading of 80 and 9.5. I tested my bg today for the first time using the machine I bought and it read as 4. I had been fasting today (religious reasons) and am currently on 1000mg of Metformin (I have to buiild up to 2000mg over the course of a month). Could this result be possible or is the machine not working? I can see I have lost weight since my diagnosis and am on a vlcd and low carb diet , but for the last two days my eyesight has been really blurry when I try to read my lesson plans (I'm a teacher!). I really don't know what is happening.
