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.
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?
