So I'm currently waiting to start a ER night position either 7pm to 7am or 3pm 3am, I'm not sure which one for sure. If I take the 3-3 I'm not that worried about sleep. Its the 7-7 that scares me. If I get home at 8:00 how long should I sleep to? I can fall asleep in the day easily when I work doubles, just not use to doing it consecutively.
