Thank you
@Libby3781, As I understand it
levemir is long acting insulin of approx. 12 to 16 hours (24 hours at the outside) duration and
most take it twice daily so that it covers 24 hours.
Also
it has little effect on BSLS rises from meals because its effect on BSLs is low and extended, as basal insulin should do..
And
fasting morning BSL gives me information about how my evening levemir (talking some 7 + years ago) is working. I used to also say, skip lunch and see how my BSL was say, 2 hourly from 12 to 6 pm as a way of seeing how that 6 hours was going basal-wise. And same for say, 6 pm to 12 mn(no evening meal) , 12 mn to 6 am, 6 am to 12 md (no breakfast) etc. .
But
if say, my evening meal led to a BSL after 2 hours of 12 mmol/l, then I could not expect my evening levemir (or a daily levemir) to do much about that reading and a higher than normal fasting morning BSL may result the next day. Putting my levemir dose up was not going to solve that.
The beauty of twice daily Levemir though, was that that at the 12 hour mark (the next of the twice daily doses) I had an opportunity to have a different dose of Levemir. After all we eat more between say 8 am and 8 pm than between 8 pm and 8 am, and maybe there is less stress when sleeping than during the waking hours so we may not need the same level of basal through 24 hours.
So I am suggesting you
inform your DSN about what your BSLs 2 hours after each of your meals are, to see that there was not problems there and
particularly to report if the after evening meal and even the before bed time BSLs tend to be high.
And
consequently whether fasting BSL the next morning was high as well.
And about whether twice daily Levemir was a better regime or not.
High BSLs 2 hours after meals may need a different solution, I would suggest, to the use of Levemir by itself - see what your DSN suggests.
