Essay writing

It's the night before hand-in and, as usual, I'm still chugging away working through my essay. Unlike in past all-nighters there is a high probability that I will have to get up tomorrow morning, and also unlike previous essays, I know exactly what I want to write but I have no idea how to write it. The motivation comes and goes in waves and at the moment I feel myself on the downwards side of one of those waves, I just can't think of the words I need to describe what I am thinking - logical reasoning is failing me at the time when I really, truly need it.
