Knocked my coffee mug against the laptop this morning — didn't spill, but the sound made me flinch hard. A small thing. I noticed my jaw was already clenched before I'd opened a single tab.

The clench had been there since I woke up. I'd gone to bed at half eleven, which is late for me lately, and watched something for forty minutes on my phone before sleeping. I'd told myself it was fine. My jaw this morning had a different opinion. The thought that arrived with the clench was that today would be effortful, that everything would feel slightly resistant. The feeling underneath was a low, grey anticipation — not quite dread, but adjacent to it.

This is the fourth morning this week with that same shape: late screen, morning clench, the grey anticipation. I've been noting it but not doing anything with the data yet. Starting tonight I want to run a small test. No phone after ten for ten days. Parameters:

• Lights out by ten-thirty
• Phone charged in the kitchen
• Morning: note jaw tension on a scale of one to three before checking anything
• Review on 28 May

I'm not claiming the phone causes the clench. That's too clean. There's probably something about the content, or the light, or simply the stimulation arriving just before sleep — I don't know which variable is doing the work. Maybe none of them, and the clench is about the week itself.

What I'm actually curious about is whether the grey anticipation is information about the day ahead, or just residue from the night before. I'm not ready to answer that yet.

Observing tonight, mostly.
