I’m seeing a lot of similarity between my body’s use of Novolog and what @Michel has posted about how it lasts/activates in his son’s system. Seems about 45 minutes for prebolusing and it seems to last 5+ hours for me. IOB matters more for Novolog than it did for Humalog, at least for how Humalog performed for me in the last few years.
I did have two drinks Thursday night. With Humalog, I wouldn’t have needed to turn down my overnight basal for that. With Novolog, I needed a juice box at 4AM and had to lower my basal by 50% for a few hours. That was a new experience. Interesting to see that difference.
