Find the hours when your brain actually shows up
Every ADHD adult has peak hours and slump hours. Some are clearly morning brains who go foggy after 2pm. Some have a narrow late-afternoon window after a long ramp. Some peak at 10pm, which is inconvenient but real. The mistake most of us make is scheduling as if every hour is equal. That is why a 9-to-5 structure hurts ADHD brains disproportionately — the hours when the structure says “focus” are often exactly the hours when focus is not available.
This energy mapper is a simple log. You rate how you feel on a 1 to 5 scale at different moments in your day. After a week, the tool shows you your average by hour. That chart is genuinely useful — it tells you which hours to guard for deep work, which hours to schedule meetings, and which hours to stop fighting.
How to log effectively
- Log at irregular times. If you log at the same three times every day, you will only map three hours. Spread the entries across different parts of the day. A phone reminder at randomized intervals works well.
- Rate what you feel, not what you wish you felt.A 3 is “I could do steady work right now.” A 4 is sharp. A 5 is a peak hour where hard thinking is actually easy. A 2 is slow, a 1 is drained.
- Note the context, optionally.“Post-lunch, stimulant wearing off.” “Second coffee.” “Had a good workout.” The notes are where insight shows up over time.
- Log for at least a week before drawing conclusions. One day is noise. Seven days is a rough pattern. Thirty days is a real curve.
What you are likely to discover
You have a narrower peak than you thought
Most ADHD adults expect a wide peak and find a narrow one. Often one to three hours of sharp focus per day, not five or six. That is normal. It is also enough, if you use it well.
Your slump is real and consistent
The 2pm slump is the classic, and for many ADHD brains it really does land around 2pm. Knowing when your slump hits means you can route light work into it instead of pretending it does not exist.
Medication timing shows up clearly
If you take stimulants, you will see the onset as a jump in your chart 60 to 90 minutes after dose, and the wear-off as a drop 4 to 10 hours later depending on the medication. If the curve surprises you, take the chart to your prescriber.
Sleep debt has a tail
Poor sleep on Sunday often shows up as low energy through Tuesday, not just Monday. Seeing this pattern makes it much harder to underestimate the cost of one late night.
How to use your peak hours
Peak hours are for your hardest, most important work. One task. Undistracted. No email, no Slack, no meetings. For most ADHD adults, peak hours are the most valuable 90 minutes of the day by a wide margin — the difference between a peak-hour hour and a slump-hour hour can easily be 3x in real output.
Bring this insight to the daily planner. Place your peak blocks over the hours your map says are peak. Stop scheduling “deep work” for 3pm when your chart clearly says 10am.
How to use your slump hours
Slump hours are not for deep work. They are also not for collapse. They are for the stuff that takes less thought: inbox triage, admin, small tasks, tidying, walks, errands, light reading. A well-used slump hour produces a surprising amount of output precisely because you stopped trying to be sharp in it.
Pair slump hours with the dopamine menu — an appetizer or a main during a slump hour is recovery, not procrastination. The menu is built for exactly this.
Patterns that change over time
Energy curves are not static. They shift with seasons (winter slumps are real), with medication changes, with life events, and with big lifestyle shifts like starting or quitting caffeine. Keep the log running as a baseline. When something changes, the chart will tell you within a week or two.
When the chart is flat
If your entries over a week are all 2s and 3s with no visible peak, something else is going on. Possibilities:
- Sleep debt is dominating everything else.
- You are depressed or burnt out, which flattens the curve.
- Your medication is underdosed or poorly timed.
- You have a medical issue worth checking (thyroid, iron, B12, sleep apnea).
A flat chart is not a failure of the tool. It is a signal. Bring it somewhere.
Privacy
All entries stay in your browser. Nothing is uploaded. If you want a copy for conversations with a prescriber or coach, screenshot the chart.
A small ADHD experiment worth running
For one week, move your three most important tasks to your peak hour. Not mostly-important tasks. The three that would change this month if they actually got done. If you do this consistently for a week, most ADHD adults report a visible shift in how much got done, how they felt at the end of each day, and how much energy they had left for evenings. The energy map is the tool that tells you where to place them.
Pair with
The energy map becomes more powerful when combined with the medication tracker (does the curve change with timing?), the hyperfocus tracker (does hyperfocus only happen during peak hours, or can it hit in slumps?), and the sensory checklist (is a slump hour actually a sensory-friction hour?).
