I am exhausted - usually when I have pushed it too far, it takes about a day and a half to get back on track. I am now on day 3 with not a lot happening. I am also beyond speech, so I have noticed - something else that happens when it's gone a bit too far. My ability to talk coherently becomes impaired, though it thankfully doesn't impact upon my ability to write.
I have nine weeks left and two assignments and 50% of my major dissertation to do. Trying not to run away screaming tbh. I will stay, however. I have to get through to the other side of of this. Maybe it's just sunk in that my life for the past five years is about to be brought to a close. The job market is a very different place than it was half a decade ago. Maybe there is part of me which is unconsciously starting to flap.
Right now, I am snuggled with a hot water bottle and my dental guard in to stop me grinding my teeth, which I am apparently doing during the day as well as the night.
