Hi,
My first point is that you seem to have been flat overnight as there is no difference between 7.9 and 8.0.
My second thought is, when exactly did you test before breakfast? The most reliable reading is immediately you get up and before any pottering about, showering, dressing, or making breakfast.
What exactly are you worried about - your bedtime reading or your morning one? Your bedtime reading is a bit high, so if you can get that down, your morning fasting levels should improve.
The glucose dump or dawn phenomenon is where your liver dumps glucose in your system when it thinks you are "starving" and need help to wake up and start the day, or sometimes later in the day if you haven't eaten for a long time. If you type Dawn Phenomenon in the search box it will throw up a lot of threads about it.
