Another great post by Adam Brown! In our case, Nighttime management is tough due to all the physical training and games my son plays, we have more than 1 basal program depending on how the day went.
How do I stay in range while sleeping?
" What makes nighttime BGs profoundly difficult is that they are influenced by a number of factors: food during the day; dinner and nighttime snacking (size, type, timing); daytime exercise; insulin dose and timing; and more. Basal insulin requirements can also change drastically from night to night – in studies of automated insulin delivery, people with diabetes sometimes need half as much basal insulin on some nights and twice as much insulin on other nights. This makes repeatable perfection challenging!"
