I used to only write something down when something happened. Bad week, side effect, weird mood — those got logged. Quiet weeks I left blank, because what's the point.
Took me about a year to realise the quiet weeks are the baseline. Without them, the noisy weeks have nothing to compare against. When week 22 was rough, the run of 'normal' entries either side of it was the thing that made it visible — both to me and at the next prescriber appointment.
If everything's blank, every week looks the same on paper. So now I write 'normal week, nothing to flag' and that's the entry. Two seconds.
Not skipped. The boring weeks are the contrast that makes the unboring ones legible.
