Oh, dear

Last night's sleep was interrupted for about 3 hours, from 2-5 am, and I am not sure how I am going to function today. There is no reason for this sudden burst of insomnia - I'm busy at work so maybe have a lot on my mind, but it's been worse, and there was nothing in particular shoving its way to the front of my mind as I lay in bed, stupefied.

Yet, here I am.
