So it's about 4am where I am and I've been awake since 7am yesterday.  I didn't feel particularly stressed and went to bed fine, but couldn't seem to pass that threshold into sleep. 
The night has stretched on and I've accepted that I'm not sleeping anytime soon. 
I work 12hour shifts with heavy machinery and it's not safe to be there when this happens, so I'll have to call it in. 
In most things my crew leader is a stand-up guy and a I'm stoked to work with him, but if I was asked to point out one flaw in him it's that he doesn't seem to take calling in sick well.  As if he never truly believes people are as bad as they say they are and just call in to be lazy. 
It can be pretty frustrating. Feels like added stress I can do without.
