I love nightshifts!
All is quiet, nowt to bother you really, I start at ~8pm, usually finished by about 2am, used to always sleep then till the morning at work, but found it screws my bodyclock up, so just watch TV/surf net till about 6am when days come in, then I go home.
4on 4 off nights

Plenty of overtime too, did 109 hours OT in August
