Hi,
Normally i'm a "day walker." (Work wise..)
But i did do a stint nights for a while for an active logistics company just before Christmas. Had to reduce my basal by about 24%??
Had to take it an hour earlier too.. Prior, travel to work. One night i forgot the basal & had to blag a 10 hour shift correcting with Novorapid.. I use a CGM set up, regarding monitoring.
Even with the basal reduction, (Normal dose is fine on the day stuff. i had to nudge up recurring lows.
The best shift i actually had was blagging on the Novo.
Now oddly, I've spent years in bands. & normally inject my basal about 2 maybe 3 hours late on a gig night. (Normally it would be about halfway through a set.) It can be pretty energetic. ( we ain't shoe gazers.)
I fair quite well as the Lantus wears off cruising at an altitude of 4.5/5.0mmol.
