Tired and brain dead

I'm out of RAM. Need to be turned off, rested and rebooted. The last day off I had was nine days ago, and the next day off I will have is another four days from now. For the next four days, I think I will just aim for "passing." This week of working at night has been unusually busy and draining. Sigh. I'm so fatigued and getting cranky and negative. Need rest. Need rest! Four more days!
