I slept something like 12 hours last night, to make up for the 5 that I'd had the day before. Still, I simply haven't been able to wake up today. I've felt sleepy and lethargic all day. So, now that I've had supper and a bit of wine, I'm giving in to it and I'm going to bed. With any luck I'll wake up early tomorrow morning, and I'll manage to get stuff done.
