Do you test before getting out of bed or only after getting dressed, washing hands, go to the toilet, making coffe or whatever? Makes a big difference to me, my bg shoots up as soon as I get out of bed (so I test and inject before doing so). A fasting sugar and a waking up sugar are often not the same.
You've made some extremely good points about that danged "foot on floor" stuff,
@Antje77 .
It's underestimated by T1s, and some docs query whether it exists, but it does.
Before libre/cgm, one of two things would happen when I was on strips alone:
I'd wake up, test, let's say it was 5.5, I'd think ok, fine, head off to work, and then wonder why I was at 9 going in to lunch (I don't do breakfast - that's another story).
Or, I'd not bother testing on getting up (yeah, I know we should, but we don't always, do we?), find myself at 9 going into lunch, and then sit there thinking about two things: 1. the lunch correction, and 2. how the hell long was I at 9 anyway? All night, a few hours? Without doing that morning test, I didn't know.
Anyway, getting to the point. That was how it was with strips alone. A whole stack of 3 or 4 tests within a few hours to resolve it or just say that's the way it works?
With libre, though, after using it for the first week or two for obvious things like hypos, I started paying more attention to the subtler things it can be used for.
And one of those was watching just how hard that rapid 'foot on floor" spike can kick in taking me from 5 to 9 in the hour between getting up and getting to work.
I wouldn't have seen this on strips alone, but **** well saw it with libre: a definite 5 to 9 spike on getting up, so decided I'd deal with it by taking a 2, 3 or sometimes 4u pin to stop that rise, so I'm walking into lunch at 5 instead of 9.
What a difference in terms of my day to day life, and I didn't have much difficulty explaining that to docs at review, but the puzzling thing is that they didn't seem to understand that this "foot on floor" thing even existed. They just saw the number on my meter without seeing the movement in the hours around it and why I decided to take a different approach.
