-- A significant amount of good info on-line about shift work rest, sleep recommendations. Research and, experiment. Find out what suits you.
-- You're air ambulance? If you're young, night shifts are easier to deal with. Keep your weight within normal limits, if you smoke quit, don't drink alcohol -- even minimally -- during your rotation, stay fit.
-- Night flight: Don't let any manager, hospital or otherwise, make you concern yourself with "off time" or "chute time" or whatever term the knucklhead wants to give it. Rushing will bite you especially if you're battling sleep inertia (which you alluded to). Tones go off, gather yourself, prepare and, before you leave the quarters, stop at the water machine and, down an 8-ounce glass of H2O. (It's only a minimal delay and, worth it.) If you can, do same at each stop. IOW, stay hydrated and, not just summer time.
-- Go get 'em.
