I quite like nightshift work, except for the sleep issue.
Staff I work with seem to have massive problems sleeping during the daytime, and consequently get a severe lack of sleep before starting work at 7pm.
I appear to have the opposite problem, in that I seem to sleep much better during the day than I would otherwise do after a day shift.
Home at 0800 I hop in the shower, stick my uniform in the washing machine and head off to bed. If I remember to set the alarm I'll get up again at lunchtime to take the uniform out and stick it on the radiator and then go back to bed. Otherwise, I'll sleep solidly through.
I've had a few really interesting night shifts lately - apart from having to have my name added to a list of staff who closely nursed a gentleman with suspected TB (and no-one knew about it...). I just hope my BCG will protect me if it does turn out that way...
