My normal (no hormones, no travel, no stress, no huge amount of exercise etc) basal set up is:
00.00 – 1.30 u/h
02.30 – 1.00
05.30 – 1.20
11.30 – 1.15
18.00 – 1.35
So that’s a range of 0.35 over the day. It’s incredible the tiny amounts that make such a difference. And such a shame there isn’t a standard basal rate pattern that would suit us all, it’d save so much work!
