I find I am always a bit higher when I test as soon as I wake whatever time that maybe.
I used to find the DP readings got me down a tad, and set me off on the wrong foot.
Hence my no longer posting what my waking levels are every day as I used to.
I now eat my dinner in the evenings around 18:00 and do not test any more upon waking. My first test is normally before I have anything at all eat, whatever time that may be. Recently, if I do test, it is around 11:00 to 12:00 ish. So around 17 -18 hrs since my last meal.
I find this way of eating, is for me, perfect. I am no longer hungry and my levels are fairly even (around 4 to5 mml) for the majority of the day.
