Hi Juicyj,
Thanks for answering, yes T1 and pumping novorapid. This was yesterday and actually I ended up lazing around doing not much at all apart from moaning!
Kept chasing the hyper with insulin and the keytones came down eventually. Woke at around 4am tested and was still 16 keytones at 0.4. Corrected and was 8 at 8am

Today I am steadily climbing again

.
I have never heard of increasing correction bolus for higher levels but this makes a lot of sense. Is this something you were told by a medical professional or something you found by trial and error?
I usually wear the freestyle libre and would feel confident to try this method but my last one fell off on Friday last week and I prefer to start a new one when my levels are fairly consistent - so I’m still waiting......
I suspect your correct and maybe I’m ill, going to be ill,have been ill, it’s the menopause, the wind has changed direction.......lol
Thanks again I’m sure it’ll sort itself out with a bit of help from our good old friend insulin.
