Couldn't resist the title--have you noticed how sub-sub specialized medicine is becoming? Tonight I begin the first run of night shifts at Macy's (four nights in a row, a mere warm-up to doing as many as eight). I haven't had regularly scheduled in-hospital night shifts since residency Night Float rotation. I'm a bit rusty at the night routine and have to re-create the correct timing of coffee, protein-rich meals versus carb-rich meals. Meanwhile, the white noise machine and blackout curtains haven't arrived, so this weekend might be less slick than I'd hoped. Cross your fingers for me.
