Is my blood glucose attracted to 8mmol/L?

NOTE: My Libre always reads higher, the actual blood glucose value is usually 80% of what the Libre says.

What's all this about then? It always seems like overnight my blood sugars will always tend towards the 10 mark on the Libre, 8 in real life, if I start below it will drift up (although this isn't exactly drift this time, more like a rapid climb), if I start above it will drift down, and this happens until it levels me off at 10 on the Libre, regardless of my basal.

Might also be worth noting I'm probably still in my honeymoon period.
 
Have you tested around 3am to see what your BG actually is? I wonder if maybe you're going slightly hypo then getting a liver dump. On the other hand, it could be an early dawn phenomenon.

Have you mentioned this to your DSN?
 
I find each sensor differs. When you check results are you leaving 10-15 mins between? Blood first then Libre.

Yes I do, but I'm not on about the value, I'm on about that random trend upwards during last night, that always levels off at the same place every night. Sorry if that doesn't make any sense, it's a bit difficult to explain

You're possibly right with the liver dump. Is it usually random when the liver chooses to dump or is it usually a certain level it will? And does it always dump the same amount?

I haven't mentioned this to my DSN, will do when I go back to Uni which is where she is based.

The weird thing is is that whatever happens, if I go to sleep really high, or at a very good low level, and regardless of my basal dose, it will tend towards 10 on the Libre, and then level off there until I wake up. It's like my body naturally wants me at that level? If that makes any sense? I might be making some silly idea up, but it's just how it seems. I could send example of when it has done just that?

Well, you know what we always say, everyone is different. You said you're still in the honeymoon period, so that also could be influencing what's going on. Your DSN should be able to explain what's happening, but our results can also fox them at times.
 
What basal insulin are you on? How often do you inject it and at what time(s) of day?
 
I think this question of why your liver adjusts BG to 10 day after day, regardless of bedtime levels is crucial. I read that a BG of 6 or seven represents around 5g total of glucose in a whole body. So if you ate even 30g of carbs total, and you might on occasion have consumed eg 100g of sugar (let's say Christmas day..but might just be a bad day, or an angry day) where did the rest go for you to end up with only 10g left in your whole body? Your body produced enough hormones to deal with 90g. This thought occurred to me when I spent a few days in hospital and was mistakenly given IV glucose. around 70g was infused direct into my blood, I was already dealing with an infection so it was catastrophic 'treatment' but my body brought that back to 14 (my normal level) within 24 hours. God only knows how when they say I don't produce any insulin...I do wonder. Interesting YT video on glucose levels and how harmful they are compared to the meds we are given to adjust them by James McCormack, entitled "Metformin - The Case of Exaggerating Both Benefits and Harms". He has many others, I am ploughing through them all.

Lantus, once a day at around 10pm.

Hi, I'm on Levemir but I think it is true of both that they don't really last the full 24 hours, so splitting into twice daily injections may well give smoother more consistent coverage. I started at once daily, but it has been much better splitting it for me.

I've just googled and notice that Lantus has a peak effectiveness (when it is strongest) at about the 6 hour mark. So if you're injecting at 10am, and your peak may be slightly earlier... that would explain the 3.0 reading at 3am... and then you are rebounding from there.

Hopefully someone who uses Lantus can add to this.

But i'd try splitting into two injections, or at least if you want to stick with one do it in the afternoon.
 
Very interesting - I have no solutions but some experiences of my own. I also use a Libre, but the readings are much closer to the BG then what you experience. I take Lantus at breakfast time (interesting thought by Draco to split it) and Novorapid with meals or to make adjustments. I find the rapid insulin can take a couple of hours to kick in (unless I exercise, in which case it is very rapid).

Looking at my night-time trace, sometimes it goes down to about 6mM and sits there all night, hardly any dawn effect, just starts climbing again at breakfast. Other nights it can start at about 6, but then has a very steady climb up to about 10mM by 8 in the morning.

I find that if I start the day at 8mM or below it is very easy to keep control or go hypo. Starting at 10mM or above and it is almost impossible to bring it down in a controllable fashion - takes ages to come down and then gets into a bit of a rollercoaster.

I have wondered if there may be some gastroparesis going on - possibly different with different foods, but I haven't been able to specifically link it - possibly something to raise with your DSN?

I take Lantus at night at 10pm, that carries me over the 24 hours, and take Novorapid before my meals.
