If you have ADHD, you know the crash. One minute you're functional — maybe even hyperfocused — and then it's like someone pulled a plug. Energy gone, focus gone, motivation gone. It feels random, like weather you can't predict.
It usually isn't random. Energy crashes tend to follow patterns. The catch is that the patterns operate on a timescale your memory can't hold — they only become visible when you have weeks of data laid side by side.
Why the crash feels random (but isn't)
In the moment, a crash feels like it came out of nowhere because you're experiencing it as a single event. What you can't see from inside one bad afternoon is that the same dip may have happened at the same time, after the same trigger, several times over the past month.
ADHD working memory makes this worse. The brain that crashes at 3pm on Tuesday often genuinely doesn't recall that it also crashed at 3pm last Tuesday, and the one before. Each crash arrives feeling novel. Without an external record, the pattern stays invisible.
A crash you can predict is a crash you can plan around. You can't predict what you can't see — and you can't see a pattern that lives across weeks without writing it down.
What 30 days of tracking tends to reveal
When people log energy consistently for about a month, a few recurring shapes show up again and again:
The post-lunch dip
A reliable early-afternoon drop. Common in general, often sharper with ADHD, and frequently tied to what and how much was eaten at lunch.
The day-after-overdrive crash
A hyperfocus or high-output day followed by a noticeably flat next day. The crash isn't the problem in isolation — it's the predictable cost of the previous day's spike, and seeing that link changes how you pace big pushes.
The specific-day slump
Energy that dips on the same weekday repeatedly — often tied to a recurring meeting, commute, or obligation that quietly drains more than it appears to.
The sleep-debt lag
Crashes that show up not the day after poor sleep, but a day or two later — which is why they're so easy to misattribute when you're only looking at today.
Tracking turns crashes into something you can work with
The value isn't the logging itself — it's what becomes possible once the pattern is visible. If you know Tuesday afternoons reliably dip, you stop scheduling demanding work then. If you know a hyperfocus day costs you the next morning, you plan recovery instead of scheduling more. The crash stops being weather and starts being something with a forecast.

Start before the next crash, not during it
The instinct is to start tracking when you're in a slump, looking for an explanation. But like any pattern, energy crashes only make sense against a baseline of normal days. Start logging now, on an ordinary day, and by the time the next crash hits you'll have the context to see where it fits — and what reliably comes before it.
