11pm. Time to stop working.

I've worked from 8am to 11pm today. 

This isn't good because I know that tomorrow I will wake up grumpy and not rested. 

I will also be awake longer than I want to tonight making me even more tired and grumpy tomorrow 

I'm not even in my normal surroundings. Which is just great. 

All in all, tomorrow is going to be one really tired and grumpy day.
