| 2 years of it, I find shift work to be a definite negative. Especially anything causing lack of sleep or poor sleep. It's going to move your rhythyms around, period. My health and BG improved when I gave away night shifts.
The effect is going to be different for everyone. As for finding that your active nights are better than your non active nights, it suggests your insulin regimen may need changing for those nights off. What do you do dosage wise? (amount/time?)
