Been working for a week now, the job is fine, it's surprisingly not tiring but there is one problem. Sleep. When I finish I'm still not tired enough to sleep and I know I have to feed the dog at 12ish so I get an hour or two sleep before waking up again. After that I might get a few more hours but it's bloody hard to sleep.
The people are all mostly nice and friendly and the time goes pretty fast. Being tall helps a lot, means I don't have to use a Dalek / kick stool.
75% of the night shift staff seem to smoke, not sure if that's related to working nights.
