So really confused here. Returned home with bg of 6.7, had a very low carb dinner (chicken salad). I made sure there was less than 30g of carbs in the meal and two hours later reading was 9.7. 15g did come from half a white pitta, but I simply can't explain the spike. Including dinner I've had 95g of carbs total today. Anyone with any suggestions on what I've done wrong?
