I'm more a fireman than a paramedic though. Anyways when i do the paramedic job, i'm in a condo and waiting for the telephone to ring to announce us where is the emergency. So if the tel is quiet we can sleep there (day or night it doesn't matter) ..and 2,3 night emergencies are very rare, but when you have it, the next day you're a reck. The same goes when i'm a fireman, sleeping at night and if the horn yells, i wake up and equip.
