I've worked 57 hours in the last week... plus seven hours today. Eight day stretch. I'm dead. Beyond dead. I've already sat through about 3 massage cycles in our recliner and my back is feeling semi-normal again, if still tired. Now I have two days off to recover a little. More later. I'm going to take a long, hot shower and collapse. 
I thought you were now going to work a regular week of shifts. Or did you take extra shifts?
