Hi Jack, My normal fasting in the morning is in the 5s, and 2 hr post meal is also in the 5s usually, though occasionally in the 6s if I have tried a new food. From halfway between meals until I eat it is often in the 4s. Sugar and potatoes are my worst enemies, and white bread, so I don't touch any of those. I don't eat pasta or rice anyway. When I eat something different I test more, before, at 1 hr and 2 hrs. After 4 days without Metformin may try it and see what happens, butt life has been more normal since stopping it. Trial and error I think!
