Confused about Long acting insulin

[london5]

I was diagnosed type 1 Feb 23 so still fairly new. I have some residual insulin of my own and use only Lantus 10 units at night. Started at 6, then 8 and increased to 10 last 2 months or so. Was OK but last few days since friday I've had hypo after hypo 3 during the day and bumps along the bottom all night which it never used to. Woken by alarm st 3am and 4am and 6am today. Stonking headache and tired of course. I have an appt with specialist nurses 20 Nov so will ask but I font understand what's happening. Used to get a bit of dawn phenomenon, not now. I cook my own food and try to eat healthily as much as poss. I ate roast lunch around 1pm inc small amount of mashed potato, starchy veg and baked apple for desert but even now it's 10.5 after peaking around 14 and it's 7pm now. Makes me feel I can't eat, although I'm not hungry so doesn't matter.
I did have x2 crackers and marmite 9pm ish last night to try and head off hypo but didn't work and it's hard to eat jelly babies at 3am or even drink juice at least I find it hard.
I did have flu jab 22 October so wondering if that's thrown things out and I have been a bit sneezy but I don't feel ill. Puts me off getting the covid jab.
I know the spec nurses will try to help. I use a dexcom one cgm and I'm hooked up their system at the hospital but does anyone here have any insight into what might be happening ?

Insulin needs can change from month to month, season to season.

Perhaps the higher dose was right for you 2 months ago, but maybe now your insulin need has backed off a bit (more active? Less stressed? Not having a bit of a cold?).

There are no ‘right’ doses, only ones which work for what your body needs now.

In your shoes I’d be tempted to take my basal down a notch (or half). But then I’m an eternal fiddler!

As @everydayupsanddowns has said insulin needs do change all the time - I'm no medical professional but maybe talk to your healthcare team about changing when you take your basal insulin (maybe to the morning instead of evening, as you are having a lot of overnight hypo alarms) - or maybe splitting your dose (not too sure whether this is advisable on Lantus though (perhaps someone could advise?) as I split mine (on Levemir, which I'm told is fine) - defo sounds like the basal is a bit strong though so maybe think about lowering slightly

This is the trouble with just being on a basal insulin @london5 Your Lantus is probably now too high for your needs as it’s wrongly being used to mop up your meals. Far better to have both insulins - basal and bolus and use them as your body needs. That is, it’s better to have small amounts of both types rather than more of one type.

Make sure you’re confirming the hypos with fingerpricks just so you’re 100% sure what’s going on.
