I haven't been able to have my A1c checked for over a year as I've been housebound with something else and am waiting for a colostomy op. But after losing 5 stones (70lbs) through controlling sugar and carbs I am diet controlled and my BS is usually in the 4s or 5s and 6s and 7s 2 hours after eating. I was on metformin but they upset my stomach so much I had to leave them off. I keep my BS in the non diabetic range.
I didn't realise our BS could be too low with type 2, so must read up on that but for me I don't consider in the 4s and 5s too low before eating.? Once or twice it was in the 3s and felt dizzy until I ate something. Maybe I'm wrong, I'm not sure now.
