However, whether from the shingles or a deteriaton in his condition (or both?), Colin has had days of complete wipe-out, i.e. totally asleep and not able to be awoken, by anything. This happened on Monday this week, when his sister and brother-in-law visited, and a old colleague of his. He slept from about 1130 to 1700, and awoke just after his sister had left. Fortunately they were still in the vicinity so were able to come back briefly. Weirdly, Colin could remember the other person had visited, even though he appeared soundly asleep and didn't speak to him! And he had another asleep day yesterday, which means no lunch, and almost no evening meal, as well as no drinks!
So today, I am trying to keep him awake. I don't know if I shall succeed. The bathroom works does not stop him falling asleep, so I probably won't stand much chance if his brain wants to shut down. Eating and drinking require more than just being awake, there has to be an awareness of the mouth for chewing and swallowing, and there is a change to this. That's the scary bit.
Oh, by the way, I acquired a new washing machine, the tumble dryer is working again (something intermittment) and the third party who bashed into my car has paid up!
