127'ish is still a great fasting number - right at the line

If you did forget your metformin - it's sole function is to restrict how much sugar your Liver releases overnight - could totally explain why you were "up just a little" (because you still would have had a couple previous doses working - they last for about 48 hours, you just would not have "topped up the tank")

Laying in bed for a while after waking - especially if you kinda doze a bit - will cause your numbers to rise somewhat - your Adrenal and Pituitary Glands are trying to "kick your butt out of bed" and any activity from them (in the form of the hormones Adrenaline and Cortisol) call for "a bit more sugar".

Especially those of us that have pretty tight consistent fasting numbers seem to focus on that "outlier" as if it was an alien number.

Like you I'm "almost always sub-6 (under 108) and average "under 100". In fact so much so that I "KNOW" that the last time I was "over 6" was on the 27th of December when I saw a 6.2/112

While it kinda bugs the snot out of me when I see a number like that, we do have to step back.

Like Seriously - what real difference or effect does it have that on "that day" I was about 10 to 15 points higher than average.

If we look at our numbers for that Month, that is a "rounding error". 15 points would round out to an additional 0.5 points per day - our meters wouldn't even detect that.

I'm bad that way however - it tick's me when the number is unexpected - but as long as the "trend" remains - tomorrow and the next day it's back in the wheel rut that it normally travels in, we have to shake off that "totally excellent number that we really have no business complaining about because it still is an AWESOME number", maybe that is a good thing. It keeps us "engaged" 😀

Thanks Graham. Appreciate your answer.
