I have been using  Libre2 sensor for two years, probably overuse it, however when hypos are indicated from my iPhone12 and I don't 'feel it' I do a blood sugar.

During the night, after injecting 18 units of long acting insulin after dinner, I get a signal, low blood sugar, half asleep I start off with 5 jelly beans, I feel it's not working, so I dive into toast/honey + a spoonful of golden syrup. My blood sugar reading has not moved. Still feeling the hypo, I wait until blood glucose reaches 5.0 + ......Does anyone else have these night time results? Daytime hypos are pretty much ok..usually fixed with jellybeans....

Occasionally I get a reading from my Libre 2 that doesn't seem right - says 6.0 when I feel low, or says I'm 2.8 when a finger prick shows 4.6.  It is not often but when it happens it is typically later in the lifetime of the sensor, around day 12 or so. I also can get compression spikes when I lie on my side in bed (L2 on upper arm).  I try and position the L2 so this doesn't happen but some times it does. It doesn't heppen very often - maybe once every few months. Also a poor aplication of the sensor, or the sensor losing adhesion can cause unpredictable readings. I use Skin Glu or SkinTac to improve adhesion, and I use a patch to protect from knocking.
I use MDI and have adjusted my long acting insulin dosage for a flat overight, well as flat as possible) BGL. At night when there's no food or fast acting insulin affecting BGL it is purely the long acting insulin affecting BGL. If it drops overnight, take less. If it creeps up, take more. I'm talking 1 unit at a time adjustments. I also split my long acting insulin into morning and night doses.
I don't believe LibreLink has the capability to use calibration readings. The developer of JuggLuco has an email from Abbott on what they consider adequate accuracy of  Libre 2 here. (you have to scroll down a bit). His opinion is it is not useful to calibrate the sensor. Dexcom G5/G6 can be calibrated - Dexcom Calibration. I don't know about Medtronic. Third party apps like Spike, xDrip+ Diabox have the ability to calibrate, and have rules in place that a calibration can only be enetered when BGL is stable, etc.
I used to calibrate with xDrip+ but whilst it gave me more confidence in the readings, they weren't vastly different to finger pricks.
That said the time delay between a finger prick (blood) and CGM reading (interstitial fluid) is in my experience variable. I've read 5 minutes and I've read 25 minutes. So any calibration technique would have to cater for such variations which would be very difficult to achieve. Maybe Mr JuggLuco is right...

Thank you Michael and Roger - good info.   My McAfee rates the JuggLuco link as suspicious, so I haven't looked at it.  But I've done my own statistical checks on L1 and L2 with various finger prick readers and find the accuracy adequate, apart from the odd bad sensor which is easily replaced by Abbott.  We need to remember that both the finger-prick and L2 sensors measure different things and both are just an estimate of our true BGL.  The companies probably try hard to get the CGMs to agree with finger-prick results, because we have used finger-pricks as our ground-truth.  I'm sceptical about users "calibrating" their CGMs with just one data point, but I certainly don't want to discourage people from doing that.  It's wise to wait for BGLs to be stable before calibrating.

Hi Jock,

I wouldn't say Freestyle "easily replace" bad sensors. I've had 3 fail at day 10, and 1 fail at day 8 in the last 40 days. Each time I reached out to them via the web site, and each time they have just sent me a retrieval box to send the faulty sensor back, no replacement. In fact, they state it will take 60 to 90 days to investigate. I'm back to finger pricks until I can re-order. 

I'm so fed up with them I've actually gone over to a DexcomG6 instead. I've heard of so many people ditching Libre for the same reasons, premature failure and widely fluctuating readings. I've had many saying I'm sub 3 mmol, only to do a finger prick to find out I'm well and truly over 3 mmol.

I couldn't/wouldn't recommend them to anyone. If that sound harsh, it my opinion and my truth

I wonder if Libre 3 will be an improvement? Abbot should discontinue Libre 2 if it is inferior to their Libre 3. What are the benefits of 3 & what will be the cost when they decide to sell it in Aus?
