Tired, foggy and drained after the pain has gone? That's the postdrome, or migraine hangover. What it is, how long it lasts and how to recover.
The pain has finally gone. You should feel relieved, but instead you feel as if you've been hit by a truck. Your head is heavy, your thoughts are slow, you reach for words that don't come, and all you want is to lie down. You haven't had a drink, yet it feels exactly like a hangover.
If this sounds familiar, you're not imagining it. Doctors call it the postdrome, and many people with migraine know it simply as the migraine hangover.
In short: the migraine hangover, or postdrome, is the recovery phase that follows the headache phase of a migraine attack. Common symptoms are tiredness, poor concentration, brain fog, low mood and a sore or tender head. It usually lasts from a few hours to a day or two. Resting, drinking water, eating regularly and easing back into activity gently can help you get through it.
Key takeaways
- The postdrome is a real phase of the migraine attack, not just "being tired".
- Most people with migraine have postdrome symptoms at least some of the time.
- It usually lasts up to 24–48 hours after the headache ends.
- Gentle rest, fluids, regular food and a slow return to tasks are the most practical ways to cope.
- A long or unusual recovery is worth mentioning to your doctor.
What is the postdrome?
A migraine attack can unfold in up to four phases: the prodrome (early warning signs), the aura (visual or sensory changes), the headache, and finally the postdrome. We explain all four in our guide to the phases of a migraine attack.
The postdrome begins as the headache eases. The brain changes involved in migraine don't switch off the moment the pain stops. They settle gradually, and while that happens, you may feel far from your normal self.
The UK charity the Migraine Trust describes the postdrome as a common stage of a migraine attack and notes it can leave people feeling drained or "hungover".
Migraine hangover symptoms
Postdrome symptoms vary from person to person and from attack to attack. The most common include:
- Tiredness and exhaustion: feeling physically and mentally drained
- Brain fog: trouble concentrating, slower thinking, forgetting words
- A sore or tender head: a dull ache, or brief pain when you move your head suddenly
- Stiff neck
- Mood changes: feeling low or irritable, or, for some people, unusually upbeat
- Dizziness or feeling weak
- Lingering sensitivity to light or noise
- Changes in appetite, either hungry or off food
Some people also say they feel "fragile", as if another attack could start easily. If you often have a new headache soon after one ends, mention it to your doctor.
How long does a migraine hangover last?
For most people, the postdrome lasts from a few hours to about a day, and sometimes up to two days. It tends to be longer after longer or more severe attacks, but this varies.
Added together, the prodrome, headache and postdrome can mean one migraine affects your life for several days, which is one reason the World Health Organization counts migraine among the leading causes of disability worldwide.
Why does a migraine leave you feeling hungover?
Researchers are still learning exactly what happens during the postdrome. What we know is that migraine involves changes in brain activity, blood flow and chemical messengers that continue for some time after the pain fades. Brain imaging studies suggest some of these changes are still present during the postdrome.
Other factors can add to the hangover feeling:
- Poor sleep during the attack
- Not eating or drinking enough while you felt sick
- Side effects of medicines taken during the attack. Some people feel drowsy or "heavy" after certain migraine medicines. If you notice this, ask your doctor or pharmacist whether it could be a side effect
- Stress of coping with the attack, and catching up afterwards
How to get through a migraine hangover
There's no special treatment for the postdrome, but simple steps can make recovery easier.
1. Rest without guilt
Your brain is recovering. If you can, keep the day light: postpone demanding work, avoid long screen sessions and say no to extra plans. Short naps can help some people, though very long daytime sleep may make you feel groggier.
2. Drink water
You may have drunk very little during the attack, especially if you felt sick. Sip water regularly through the day.
3. Eat regular, simple meals
Even if your appetite is low, try to eat small, regular meals. Skipping meals can leave you feeling worse and is a commonly reported migraine trigger.
4. Move gently
A slow walk and fresh air help many people feel more awake. Avoid intense exercise until you feel recovered.
5. Watch caffeine and alcohol
A cup of coffee may feel tempting, and for some people it helps. But large amounts of caffeine, or caffeine withdrawal, can contribute to headaches. Alcohol is best avoided while you recover.
6. Be careful with more pain medicine
If you have a lingering ache, think twice before reaching for more painkillers, and follow the plan agreed with your doctor or pharmacist. Taking acute pain medicines on many days each month can lead to medication-overuse headache.
7. Ease back into work
If you can, plan a gentler first morning back: tackle routine tasks first and leave important decisions or meetings for later. If migraine affects your work regularly, an honest conversation with your manager about flexible arrangements can help.
How to explain the migraine hangover to others
People around you may assume that once the pain is gone, you're fine. You might say something like:
"The headache is over, but migraine has a recovery phase. Today I'm tired and slow, like after a bad flu. I'll be back to normal by tomorrow."
Explaining this calmly can reduce pressure and misunderstandings at home and at work.
Track your recovery, not just your pain
Most people only record the headache. But noting how long the postdrome lasts and how much it affects you gives a more honest picture of your migraine. It also helps your doctor understand how much of your life migraine really takes.
In your migraine diary, add:
- when the headache ended
- when you felt back to normal
- what the recovery felt like (tired, foggy, low mood)
- whether you could work, study or look after others
Bring that information to your next appointment. Our neurologist appointment checklist shows how to present it.
When to talk to a doctor
Talk to your doctor if:
- your recovery often lasts more than two days
- recovery symptoms are getting worse or changing
- you rarely feel fully well between attacks
- low mood after attacks is lasting or worrying you
Seek urgent medical help (in Europe, call 112) if, after a headache, you have confusion, weakness, numbness, trouble speaking, a severe new headache or a fever with a stiff neck. These are not typical of a migraine hangover and need checking straight away.
Frequently asked questions
Is a migraine hangover real? Yes. The postdrome is a recognised phase of a migraine attack. It's part of migraine, not laziness or "just tiredness".
How long does a migraine hangover last? Usually a few hours to a day, sometimes up to two days.
Can I go to work with a migraine hangover? Many people do, but it can help to keep the day lighter if possible. If migraine regularly affects your work, consider talking to your manager about flexibility.
Does everyone get a postdrome? No. Many people with migraine do, but not everyone, and not with every attack.
Can coffee help a migraine hangover? Some people find a small amount helpful. But too much caffeine, or caffeine withdrawal, can contribute to headaches, so keep it moderate and regular.
Recovery is part of the attack
The migraine hangover is the part of migraine that people rarely talk about, yet many people with migraine know it well. Recognising it as a real phase can help you rest without guilt and explain to others why you need a little more time.
With MIGMO, you'll be able to log recovery alongside the other phases, so your doctor sees the whole attack, not just the pain. It's available now on the App Store and Google Play. Read more guides on the MIGMO blog.
