Well it's a pity you didn't meet your goals, but don't be too upset - not only is 5.7% lower than most other diabetics, it's also lower than some non-diabetics! You aren't doing much damage to yourself, and a stable 5.7 is a pretty safe number to be at. Also, remember that once you get your HbA1c down to good levels, it's more about quality of life than getting that extra 0.1% improvement. I used to be 4.6 but I had a lot of rapid drops, and some hypos. These days I'm at 5.1, and like you I felt that maybe I had been a bit lax in my control, but in reality I haven't had any scary hypos and life is a whole lot better (=less scary!). Don't worry about your HbA1c too much - it's the day to day numbers you get that really matter. If you're happy that you aren't getting particularly low or high then that's the real achievement. If you are a good diabetic and put in the effort, HbA1c doesn't tell you anything you don't already know.
