A few days before we left America, The Twitch came back. It’s something I get when I’m not getting enough sleep: a pulsing in the lower eyelid that drives you nuts but that other people generally can’t see. But this time it’s got creative: instead of a single twitching eyelid, my eyes are taking it in turns. So Monday is the left eye, Tuesday is the right, Wednesday is left again and so on.

It’s been going on for nearly a fortnight now, so naturally I’ve done some digging to find out what causes it. And according to medline, it’s caused by the combination of too little sleep and too much caffeine. Which means it’s caused by MY LIFE. Great!
