Hi
@Cathy Cally,
Hopefully a couple of bits that might help.
Libre 2s are not always accurate above and below normal range - I find 'high' BG and they give you a big number (so you know you're up with the light fittings), but your blood BG is the accurate one.
At night your body isn't using as much energy so if your slow acting is too low, it will rise, then keep rising as time passes, till some more insulin kicks in (or your start moving around in the morning and inject a bit of insulin to knock it down again).
The higher you are, the less effective insulin is, so you often need more to get BG back down.
There is also something called 'Dawn Phenomenon' where your body is getting ready for you to wake up - and gives you a boost of stored energy (BG goes up) an hour or so before you normally get up in the morning. Not all of us have problems with this, but lots do - so worth being aware if that impacting you - check your Libre graph and see at what point you're climbing, and if its a steady climb
Sounds like you need to talk with your DSN to get your Basal set right - its really difficult to get initial levels right when you start, give it time and you'll get there. Been doing this 50 years (you will survive it

), you'll be ok once you level it all out and can feel more confident about changing things to suit your own body
