What not to do after a migraine: the postdrome mistakes that backfire
Skip the extra dose, the caffeine push and the hard reset. What to avoid in the after-phase, and where the rebound-headache line sits.
What should you avoid after a migraine?
Avoid three things in the hours after the headache lifts: taking another dose of your acute medication for leftover heaviness, throwing yourself straight back into a full day (hard workouts, long screen sessions, skipped meals, a wrecked sleep schedule), and propping yourself up with extra caffeine. The postdrome is still part of the attack. Treat it like the all-clear and a bad day can stretch into a bad week. And a few extra tablets a month can add up to rebound headache.
Most people get some version of this phase. In an electronic diary study published in Neurology in 2016, Giffin and colleagues found that 81% of patients reported at least one non-headache symptom after the pain resolved, with tiredness, trouble concentrating and neck stiffness among the most common.
So the fog is expected. The mistakes are optional.
The postdrome do/don't table
Each row pairs the reflex with what usually goes better. None of it is a cure. It's damage control for the day or two when your head is still recovering, and it's a list you can hand to the partner who keeps asking why you're still off.
Your neurologist's plan beats this table every time. If they've told you to repeat a dose under specific conditions, follow that.
Don't
Do instead
Why
Take another triptan or painkiller for the leftover heaviness
Treat it as a medication day you've already used, and ride out the residual pressure unless your plan says otherwise
Every extra day of acute medication counts toward the medication overuse thresholds
Drink extra coffee to cut through the fog
Keep caffeine at your usual daily amount
Swings in caffeine intake (up or down) are linked to headache, and caffeine-containing combination pills count toward overuse
Go straight back to a hard workout
Walk or stretch gently, and save intense training for when you feel level
Strenuous exertion is a reported trigger for some people
Sleep 12 hours, or stay up late to catch up on work
Go back to your normal bed and wake times
Irregular sleep is one of the most commonly reported triggers
Skip meals or run on empty
Eat plain, regular meals and keep water nearby
Missed meals and dehydration are common triggers
Max out screen brightness and clear the whole inbox
Dim screens, use dark mode, and do the low-stakes tasks first
Residual light sensitivity and slowed thinking often linger
Have a drink to unwind
Skip alcohol until the after-phase clears
Alcohol is a frequently reported trigger
Log the attack as over when the pain stops
Note when the fog, fatigue and neck stiffness actually lift
The headache end time understates how long the attack really costs you
Trigger notes reflect commonly reported migraine triggers; individual triggers vary. Medication thresholds per ICHD-3. Your prescriber's instructions take priority.
The rebound trap: an extra dose for leftover pain
The most expensive mistake looks like the most reasonable one. The headache is mostly gone, there's a dull pressure behind one eye, and the triptan is right there on the counter. Taking it feels like finishing the job.
The problem is the monthly math. The International Classification of Headache Disorders (ICHD-3) counts [medication overuse headache](/glossary) by the number of days you take acute medication each month. One tablet on a postdrome day uses up a whole day on that count. Stack enough of those days and the medication that ends attacks can start sustaining them.
If frequent attacks keep pushing you toward those limits, that's a prevention conversation. Preventive treatments that target [CGRP](/glossary), a peptide involved in migraine pain signaling, are one of the options clinicians reach for when acute-medication days keep climbing.
15+ days/mo
Simple painkillers (acetaminophen, aspirin, NSAIDs) before MOH criteria are metICHD-3 (2018)
10+ days/mo
Triptans, ergots, opioids or combination analgesics before MOH criteria are metICHD-3 (2018)
3+ months
How long that regular overuse has to continueICHD-3 (2018)
Rebound risk: don't change medication on your own
If your counts sit near these thresholds, talk to the clinician who prescribed your medication before you stop, cut back or switch anything. Some medications need a supervised plan to come off safely.
Mark when the fog lifts
Most trackers close the entry once the pain score hits zero. That's the wrong timestamp. If the pain ended Tuesday afternoon and the fog held until Thursday morning, the attack cost you nearly two more days than your log shows. Those are the days your neurologist needs to see, and the ones an employer or disability reviewer will ask about.
It changes the medication count too. A log that only records headache days hides the after-phase doses, the 'just to take the edge off' tablets that quietly move you toward the monthly threshold.
Postdrome keeps the timeline running after the pain stops. Fatigue, brain fog, neck stiffness and light sensitivity sit on the same record as the headache and every dose you took, so the rebound math is visible before it becomes a problem. Aura Mode keeps logging usable when your eyes aren't, and your data stays on your phone.
When to call a clinician
Fog and fatigue that ease over a day or two are expected. Call your doctor or headache specialist if:
- you're using acute medication on more days than the thresholds above, or reaching for it more often month to month
- the after-phase is getting longer, or your attack pattern changes noticeably
- confusion, weakness, numbness, trouble speaking or vision changes are new, or don't fade
Get emergency care for a sudden, severe headache that feels like the worst of your life, a headache with fever and a stiff neck, or any new neurological symptom. This page is general information and can't replace your own treatment plan.
Track the whole attack, including the part after the pain
Postdrome is a migraine tracker built around the part most apps skip: the hours and days after the pain stops. It logs fatigue, brain fog, neck stiffness and residual light sensitivity on the same timeline as the headache and every acute dose, so your medication-day count and your true attack length are both visible. Aura Mode keeps logging usable mid-attack, data stays on-device, and pricing includes a lifetime option instead of a subscription you can't get out of.
