@Robin It is really interesting to read of your experience (there are a lot of similarities in how our respective diabetes behaves) as I have been experimenting with this and haven't had any evening Levemir for a few days now. I definitely see a noticeable DP without it, rather than the FOTF I would get with overnight Levemir and my levels mostly sink into the 4s (Libre sometimes suggests 3s) at that 3-5am period. I think I am happy with that situation as I think it is normal (ie not diabetic or diabetically managed) as long as levels aren't rising off the scale in the morning. I think exercise and good sleep definitely help it. If I don't sleep well, I don't get that dip so I think that dip means that my body is resting well and as you say, the liver pretty much shuts down and the longer the dip the deeper the sleep. I do also think that this is a rhythm for my body at this time of year but isn't necessarily applicable in other seasons.
7.4 for me this morning with an upward sloping arrow after no Levemir again last night. Reduced my morning basal back down to 22 as I hypoed 3 times (according to Libre
🙄) yesterday, so putting it back up to 24 yesterday was not a good move. Shot myself 1.5 units Fiasp for DP/FOTF and it has leveled out at a nice 5.6 now. Not having breakfast till later today, so we will see what happens. Off for a yomp up the hill to feed beasties and then do some hedge cutting (Loppers, shears and High Vis vest at the ready, since it is on a busy main road).
@eggyg I had problems initially because I used my last self funded one before I ordered a prescription and I can't reorder early either so it was all quite tight for a while. Then I had a failure on about day 10, so had to manage on test strips for a few days and then my replacement came plus I then had my prescription, so I now have plenty of overlap. You could try a custom request to release the prescription a few days earlier "just this once" (it will likely depend upon your surgery's system) or just accept that you might need a few days of finger pricking at some point. A Libre break occasionally is not always a bad thing, although the first night I always feel quite vulnerable. Or, of course, you could self fund one to tide you over.
