I agree with what the others said – it is just a number. Just take one test at a time and don’t worry about what the previous one was or what the next one might be.
I think it is good to set goals, but it is not good if you beat yourself up if you don’t meet your goal. The important thing is not whether or not you made it, but the fact that you tried to do it. There are so many things besides food and insulin that affect our blood sugar and you can’t control everything. Just do the best you can.
As some of the others said, low carb really does help with BS. One thing that I have done over the years is make the day that I go to the doctors or for blood work every three months treat day. It isn’t that I stop testing or skip insulin, but if I am hungry to pizza or ice cream, I will have it and not worry about it. Because I live alone, I don’t get more than what I can eat in that one day and if I have leftovers, it gets tossed.
