So a hard day ahead for you then, and maybe a long one too.
Might be because your bodyclock is out of sync with doing all different shifts, or you know that when you're working an afternoon shift you won't be on until the same time next day, and so can enjoy a relatively long rest.
No, a long day is boring. Quick day when there is lot of things to do.
I don't know.. When I don't work, usually I sleep like in afternoon shift, going to bed around midnight, waking up at 10-11 am.. like in these days. Probably that thing.
