Flatline club....

Min-max this year has been 3.9-5.6 respectively. Most days I’m between 4.5-5.5 irrespective of circumstance. My diet is probably best decsribed as paleo with dairy. Settled into the requisite lifestyle and can easily sustain it for life. Very happy with things as they stand

Hi @Cobia , I’m assuming a member of the flatliners would ideally be someone with CGM. I’m a type 2 and just fingerpick test between 4 and 8 times a day depending what is going on with my life. I love a good graph though, so I give you my average daily blood sugars for the last month, ranging as usual between 4.9 and 5.4. Please ignore the 14th, 15th and 16th Feb when I had surgery followed by a sick and painful couple of days. I will watch this thread with interest, as I say I’m a bit of a number geek with a penchant for a graph or two. One day I’ll treat my self to a libre!

Lol, @Cobia , we sometimes joke about #competitiveflatlining over on the Type 1 Stars R Us thread!

I'm fairly relaxed about the occasional bounce out of my 4 to 8 range as it doesn't matter that much in the wider scheme of things, heck , even non-Ts visit 9 occasionally after meals, but it is aesthetically pleasing to throw in a tight 100% TIR with low sd every now and then.

I'm interested in the pgs metric, personal glycemic state, which XDrip+ reports. It's a dexcom thing, wrapping mean bg, variability, TIR and hypo frequency and severity into one number via some hideously complicated math. I can't find much written about it apart from this link which suggests there's a range of 4.6 to 40, 4.6 being non-diabetic, 40 being widely variable. I quite like having these numbers available - docs see a low a1c and assume it's because of lots of hypos, so it's good being able to say, no, it's because I don't go above 8 or 9 that often.

Here's a few of mine with some comments - if only they were all like that!

I can tell from the treatment markers that this was on a Friday night following a few beers, always a tricky situation with the liver prioritising alcohol over glycogen release, but looks like the two pieces of cheese on toast were enough to keep me steady throughout the night.



One of the first things I learned from cgm is that I get Foot On Floor, a variant of dawn phenomenon, big style - I can wake at 5 or so and it'll easily ramp up to 9 within an hour. I don't do breakfast, I'm not a morning person, so I could be going into lunch well out of range. I've figured out that 2 to 3u on getting up pins it well most of the time, and the 2u at about 8:45 in this pic has done the trick - that DAFNE stuff about not injecting without food is dated. A 20 min pre-bolus for a guesstimated 45g of what was probably brown rice and some salad options from the cafe next door to work led to a pleasant no rise at all afternoon, although it's just part and parcel of T1 that the same meal and same dose next day might be wildly different.



I've been playing around with my basal a lot more these days (am mdi so can't tweak it daily). When I was dx'd 30 yrs I was told that basal dose doesn't really matter that much, you can't overdose on it. Hmm, cgm says otherwise. I've been getting major differences just tweaking by 2u or so. I've noticed a few overnight traces where there is a long slow decline from 6 to 4 over a few hours, 6g nudges it back up to 6, then it declines back to 4 - clear indicator that basal needs raked back a bit. And then hopefully it settles down to something like this:



This one didn't happen, nope, malicious Chinese hackers inserted it into my cgm...

What's interesting about it, though, is that even though it is a wild rollercoaster, and the previous pic is a nice smooth line, the average bg and the estimated a1c are more or less the same, which shows how limited a1c is as a measure of control - it pays to look at other numbers as well like TIR and standard deviation.
