The first half of last week was a good one. You got ahead on work, answered the emails you’d been avoiding, cleaned out the closet, and still made dinner. You thought: finally, this is how it’s supposed to feel. I’ll keep this up.
Then Thursday arrived, and you couldn’t make a simple phone call. By Saturday you were on the couch wondering where that other you went; the one who could function “normally.”

If that’s familiar, you’re not alone, and it may not be a discipline problem. Many adults with ADHD describe a boom-and-bust pattern: a stretch of high output followed by a crash. It’s one of the most common things I hear in my work, and it’s one of the most misunderstood. I describe it to clients as a seesaw: sometimes you’re up and getting things done; other times, you’re down and struggling to move forward.

What boom and bust looks like

The boom is real. You’re focused, fast, and capable, and it feels like proof of who you “really” are. The bust feels like proof of the opposite; it affects your self-esteem and leaves you reeling in guilt and shame.
Because the boom is so good, it’s easy to treat it as the baseline and the bust as the failure. That framing can make people try harder, push longer, and crash harder.

Why it may happen with ADHD

Good days run on urgency and interest. Many ADHD brains start more easily when something is urgent, new, or emotionally charged. That fuel works, and it can produce an impressive day. It also burns fast.
You may not notice what you’re spending or that you need to recharge. When you’re in hyperfocus or running on adrenaline, signals like hunger, tiredness, and overwhelm can go quiet. You may not feel how much you’ve used until the push is over.

Good days become catch-up days. When you finally have energy, the pull to use all of it on the pile you’ve been avoiding is strong. It makes sense. But a day spent clearing the whole backlog can leave nothing for tomorrow.
Systems get built on your best day. A plan designed for peak capacity can quietly fail on an ordinary Tuesday. Then the failure feels personal, when it may just be a mismatch between the plan and the capacity.

What pacing actually means

Pacing doesn’t mean doing less forever, and it doesn’t mean slowing down because you’re weak or lacking motivation. It means matching how much you do to the capacity you actually have, and spreading effort so you don’t have to pay it back all at once.
Think of it like a phone battery. You can run it down to 2% every day, but it won’t hold a charge for long. Pacing is plugging in before it dies, not after.

What the boom and bust cycle can look like

You might notice:
• A great week followed by a week where everything feels hard and at times impossible
• Starting new systems with excitement, then dropping them, followed by shame or guilt
• Skipping meals, breaks, or sleep on good days because you don’t want to stop the momentum
• Feeling irritable or numb the day after a big push
• Healthcare workers and other people in high-demand jobs often describe this after a run of long shifts: everything held together at work, then nothing left at home

None of this means you’re lazy, lack willpower, or are inconsistent. It may be a sign that the pace and the capacity weren’t matched.

What may help

Think of these as small experiments, not a new system to fail at.
1. Set a stop time before you start. On a good day, decide when you’ll stop, ideally while you still feel capable. Then set an alarm for the stop time. It’s much easier to stop when you still have energy than when you’re out of it.
2. Leave something on the table. Finish the day with one task you could have done. It can make the next day easier to start.
3. Plan a lighter day after a heavy one. Put it on the calendar in advance, so it isn’t negotiable on the day.
4. Take breaks before you need them. Food, water, a short walk. These are part of the work, not a reward for finishing it. Schedule them and set alarms to help you know when to transition into and out of a break.
5. Build a “floor” version of your plan. For a hard day, what’s the smallest version that still counts? Read one page, pick three priorities, choose something you can pick back up without starting over.
6. Watch for your early signs. Shorter patience, skipped meals, a “just one more thing” feeling. Make a habit of checking in with yourself several times a day. Noticing early is how pacing begins.

If you’re curious where the time goes on your good and bad days, try keeping a note for one day of what derailed you: a transition, an interruption, misjudged time, or trouble getting started. The pattern often shows up faster than you’d expect. I wrote about the other side of this in my blog Rest vs. Recovery.

Closing reframe

The crash isn’t proof that the good days were flukes. It may be information about what the good days cost you.
Many people with ADHD have spent years being told to try harder and be more consistent. Learning to pace is a way to stop judging yourself by your best day and start building a life that works on your hardest one.
