A few days,ago I posted details of how my normally regular 5 5-6.5 blood sugars had suddenly risen to 6.9 and even a 7 2. I had a small increase in snacking carbs in the main almonds, an extra square of chocolate (oooh) and watermelon. I received some helpful advice. At the same time I decided to open a new box of testing strips, and to my amazement the sugars immediately returned to usual 5ish number. Is it possible that those testing strips were duds? Or cutting down the snacks changed things so quickly. Ever cautious I will continue to test just in case... No end to learning. But once again thanks
