Thanks, guys.
I feel so bad,. It's just a cold really, but it's a stinker and has gone to my head, sinuses and chest all at the same time. I got up for breakfast (which I couldn't taste!) and then went back to bed. I've been reading and dozing on and off all day, but I've got up for a bit of lunch (which I also couldn't taste!) and thought I ought to try to stay awake so that I sleep later.
It's lucky that a) my husband is working away this week so I'm not keeping him awake at night (although I miss his warmth), and b) I'm not working again until Saturday when hopefully I'll be over the worst of it. I got a couple of 'ping pings' for the kids (microwave meals!) when I knew the cold was coming, just in case, so they can fend for themselves (although both can cook proper food if they feel like it!).
I have managed to read 88 pages of The Ruins of Time by Ben Woolfenden between sleeps, so it's not all bad!
