The sleep problems I mentioned here have returned with a vengeance. I only got three or four hours sleep last night; after that, I lay awake for hour after hour, wondering why I wasn’t nodding off. And then I realised: at the cafe, I’ve taken to drinking an espresso followed by a Cappuccino – I like the way the espresso assaults the palette followed by the smoothness of the Cappuccino. I have both with sugar, of course. Yesterday was a busy day, out and about filming in the park, so over the course of the afternoon I must have had three or four of these combinations. I felt no immediate effect. It wasn’t until about four this morning, lying awake in bed, unable to keep still and wondering what the hell could have caused me to be like that, that I realised.

Well, that’s it: time to stop drinking caffeinated coffee; time to nip it in the bud, just as I did with alcohol, at least for a while. Smeg knows how I’ll cope today: I’m up early, I’m already shattered and I have a film to finish. I suppose it’ll teach me not to get silly with stimulants. Oh well, I’ll probably be okay – I just hope I’m right, and that I sleep better tonight.
