anytime my work schedule or location has changed i make a point of getting up much earlier than i need to on the first day so i can figure out how much time i actually need for getting ready before leaving for work if i discover that i need to wake up 2 hours before leaving the house thats what i do for the entire time im on that schedule and i change nothing  i do everything in the same order even make the same breakfast each day i have less anxiety about how much time i have to do stuff this way and my clocks are 5 minutes ahead for some extra insurance because i still have a tendency to still forget shit and need to run back into the house lol
