need help changing insulin time

[Simba the ging]

hi everyone,
my work schedule has changed and Simba's current food/insulin times no longer work with my schedule.

What's the best way to change the times? he's currently getting insulin/food at 6A&6P.
needing to change to either 8&8 or 9&9

thank you

You can adjust shot times by 15 minutes per cycle or 30 minutes per day. So to change by 2 hours, it would take 4 days
