Try waiting 2 hours after your meals to check sugar. You give it time to rise & then fall/stabilize back to your normal levels. Are you experiencing any of the high blood sugar symptoms like nausea, dizziness, weakness, anxiety, sweats, chills? Like you've come down with a bad flu?
Hi, your fasting and post eating numbers reported are completely normal with your regular diet.
When you ate high carb food (popcorn covered in caramel) you blood sugars did go a little higher than absolutely ideal, but not to a worrying level.
What does this tell you? it tells you that you should avoid / limit very sweet and high carb foods.
Hope this helps.
