Sleep fail

Why is this, I wake at 02.30, wide awake so get up for my usual night-time herb tea. Back to bed for more ceiling staring. I don’t get it, I’m not stressed, don’t have any worries and it’s been 12 hours since the last coffee. What’s going on?

Here is the plaster in the kitchen. And here it as was a week ago:

I suspect that the heat may have played a part it that plaster becoming detached. This is where the boiler used to be mounted and those pipes carry very hot water. I’ve not decided how to box in the pipes. Should they have insulation.

Is this a cold causing sleep disruption? the current cold has hung on a while just entering its third week. I’m so frustrated by this.
