Hi I am having issues too with high reading upon waking with symptoms of lows in night. Advice from hospital is to keep increasing Levemir dose at night currently 12units . I feel it may be better to split dose or take it am instead ? Daytime readings mainly ok and whilst I find LCHF diet works best hospital say it's wrong ? My weight is 64kg and not an issue . I am confused about what to do any help gratefully received!!
If you are going low overnight and then high first thing, it sounds like the Levemir amount you have is too high and you are suffering from going low overnight, your liver kicking in and bringing you out, and then dawn phenomenon on top pushing you high in the morning.
If you are going low overnight, then you really shouldn't be increasing that insulin dose.
To confirm this you should undertake basal testing.

If what I described is happening, I would suggest lowering your overnight insulin initially and then potentially splitting your insulin into two doses.Are you sure there is no rapid acting insulin from a late meal involved?
