Great question, and thank you for bringing that up.
For those who aren't aware: I had previous issues with (what I considered to be) dawn phenomenon, and previously had to give myself a 1-2unit injection nearly even morning or I'd see a a jump to 10+ without even touching a bite of food. I believe it was
@tim2000s who suggested that it might not be dawn phenomenon and that I should consider a change in my basal injections.
To answer your question: the new approach is working GREAT and I rarely have to give myself a morning bolus anymore. HOWEVER, I have made other necessary changes as well. It seems my morning blood sugar increases were largely attributed to eating healthy (25g+) amounts of protein just before bed. While that satisfied my hunger, the theory is that my body converted the excess protein into glucose (gluconeogenesis) only to be released by my liver in the mornings when I woke up.
I increased my morning basal injection (from memory I think it was 1-2 units), try not to eat so much protein just before bed, and I try to get at least 3-4 miles of running in everyday (in addition to my heavy weight lifting). The running is sometimes a pain in the a**, but it has done wonders for keeping my insulin requirements and blood sugar readings low (in a good way of course).
In contrast, if I do have a big meal the night before, I'm likely to get the morning spikes and will need to give myself a small (~1u) bolus. My insulin needs also change significantly (as much as 50%) during the weeks I'm less active.
