As I understand it, the liver delivers glucose to the body in response to its need for it. So fight or flight, your body needs energy fast and that means glucose. Similarly, if you’ve fasted, eg overnight, you get a release of glucose from the liver, sometimes called a liver dump or dawn phenomenon. Just getting out of bed requires energy. There is nothing wrong with raised glucose levels, provided they aren’t a high spike followed by a sudden crash. You need to use the given energy. You are doing very well with your results already. Don’t beat yourself up about it, stress raises your glucose levels as well. I’ve just spent a high stress 10 days and my glucose was around 15 the whole time. It’s coming back down slowly to within range but the more stressed I got about that, the worse it got. Good luck, you are on the right track
