Hello kplants, I looked at your profile. We both test 12 times per day. We obviously want to get good control and frequent testing helps.
I do not know your age but I am 67 and as I have grown older my Humalog takes longer to do its thing. Not that many months ago I would wake up with a good level (80-110) and eat about 40 carbs at breakfast. Two hrs. later I was 160+ and sometimes 200+. I found that if I did not take any additional Humalog at that time I would drop to the low 100's by 11pm. Now I take my pre-breakfast Humalog an hour ahead of time. Two hours later I am in the low 100's because my insulin has been working 3 hours. That has solved my problem with post breakfast highs. If the insulin takes even longer to be absorbed in the future I may have to take Humalog 90 mins. or even 2 hours before breakfast.
If any of you have trouble with the Dawn Phenomenon then you might want to look at the following site:

Good luck to you!
