@Circuspony . HbA1C is not just about insulin. Diabetes is not just about insulin. There are other things to consider when aiming for a lower HbA1C. Food and exercise will play a great part in your results.
Personally I feel that living with diabetes needs to be fun and doable
If trying to get an HbA1C below 50 causes you to be totally unhappy and frustrated whereas achieving 53 is easy, comfortable and lets you be a happy bunny then for me personally I would go for the 53. Get to 53 and hitting 50 will be far easier with a little bit of effort and not burning yourself out.
Being diabetic is not a death sentence but it will feel like one if you let it.
Please don't rush with your diabetes, carry on doing what you are doing now and chill out.
I wager your next HbA1C ' s will confirm that all is good.
