Friday evening I had a big paper due for school, so I worked very late, until about 1:30am.
Late that evening, around 12:30am I started creeping up. During the day, the first thing I do when I creep up is to up my temp basal to a high level, then cancel it later when I see it was a false alert, or when I creep down (I do that because, any time during the day, I am at risk for hormone spikes: the earlier I increase my basal the better to control these). So I dialed a +35% temp basal for 12 hours.
I submitted my paper around 1:30am, then decided to relax in bed for a few minutes before turning in by reading a book while listening to music on my phone. Because I was very tired, I fell asleep right away, with my +35% temp basal on.
Luckily my dad follows my CGM and noticed I got low a bit later.
So, after thinking about it, I decided on a change of process for temp basals. They are very important to me for dealing with hormone peaks. But, now, instead of automatically dialing them out 12 hours when I use them to prevent a possible peak (or for any other reason), I time them to end around bed time or shortly afterwards. In the evening, I dial them for a short time (1 or 1.5 hours) even if it forces me to start them again later. This way, I don’t run the risk to fall asleep with a high basal on for long.
