It is 1 AM when I finally close my weary eyes. I am utterly, completely exhausted. In the past few days I burned up the little reserves I had, working too hard, recognising the signs but pushing myself because I don’t ever learn. My eyes, interface to the world and thereby the only thing keeping me sane, twitch and shudder. I entertain the thought, not for the first time, that the ALS has spread to my eyes. Anyway. A night of good, uninterrupted sleep will do me good.
