Anymore I typically am not using combination approaches due to my big picture tracking of things. If I’ve seen my breakfast bolus start to lose efficacy over a few days, I’ll just start with adding temp basal bc it’s what is historically needed, and it does the job. But if I wasn’t adding that temp basal, the amount of correction boluses would far exceed the amount of basal insulin I’m getting and it wouldn’t come close to producing the same results. Which is what makes me think the hourly basal has to increase to handle the general resistance from the hormone factor…but it’s amazing that such a small hourly change produces such large-scale results. Which doubly means that the margin of error is quite small…as evidenced by my tanks this week.
