Alcohol and migraine: what the research says and how to record drink days and attack days honestly

After a glass of wine the head pain comes, and you ask whether alcohol is your trigger. You can record drink days and attack days on paper or in the migraine diary in Sam. There, an entry made today also shows last night's sleep and HRV from Apple Health when a value exists. This guide says what the studies on red wine, timing and triggers show. It also gives you a record to take to your appointment.

It is general information. Whether alcohol plays a role for you is a question for your neurologist. Nothing here recommends drinking alcohol as a test.

How many people with migraine name alcohol as a trigger?

In a survey from Leiden published in the European Journal of Neurology, 35.6 percent of 2,197 people with migraine named alcoholic drinks as a trigger. It was a one-off online survey, so people answered from memory. More than 25 percent of those who had stopped drinking, or never drank, had done so because of a suspected trigger.

A review from 2008 draws the same broad picture. In retrospective studies, about one third of people with migraine report that alcohol sets off attacks at least sometimes. Only about 10 percent say it happens often.

Is red wine really the main suspect?

In the Leiden survey wine, and above all red wine, was the drink named most often. Yet red wine reliably triggered an attack in only 8.8 percent of participants. The authors conclude that one drink alone is not enough as a trigger. It may depend on a shifting threshold.

The front-runner also varies by region. In some countries red wine is named most often. Studies from France and Italy name white wine or champagne instead. The 2008 review reports regional differences and no single drink that is consistent across studies. Sparkling wine, spirits and beer come up too. Explanations based on ingredients such as biogenic amines, sulphites or flavonoids are not conclusive, it says.

How fast does an attack come, and is it a hangover?

In Leiden the attack began within 3 hours in one third of participants and within 10 hours in almost 90 percent. This held whatever the drink.

The International Headache Society distinguishes two forms. An immediate alcohol headache appears within 3 hours of drinking. A delayed hangover headache starts from about 5 hours. People with migraine can struggle to separate a triggered attack from a delayed alcohol headache, because the symptoms overlap. A record with times lets your doctor see the gap between drink and start. It is their job to interpret it.

What did a diary with over 40,000 days show?

A study in the journal Headache used diary data instead of memory. The authors are linked to Curelator, the maker of the N1-Headache app that collected the data. It included 487 adults with episodic migraine who drank alcohol and tracked headache and alcohol for at least 90 days. Together that made up 5,913 attacks across 40,165 recorded days.

In the 24 hours after alcohol there was no significant effect on the chance of an attack. Between 24 and 48 hours after alcohol an attack was a little less likely (odds ratio 0.75). That is a statistical pattern in this group, not a sign that alcohol protects against migraine. These are group values, not a statement about any one person.

The authors name limits themselves:

• The group mostly drank little. 87.9 percent described their intake as moderate.
• Most were women and English-speaking.
• People who did not drink were left out, including those who avoid alcohol because of a suspected trigger.
• Drinking on the same day was not analysed, so a very fast onset can go unseen.
• The amounts were not standardised.

The survey and the diary study ask different questions and cannot be set equal. What counts in the end is your own course, and the honest way to capture it is with a record that includes times.

How do you keep a drink-day and attack-day record?

One line per day, on days with and without alcohol. Days with no drink and no attack belong in it too, exactly as in the diary study. The record only writes things down. It is not an instruction to try alcohol. The NHS says a migraine diary can help you work out what might trigger your attacks.

The gap windows match the two studies. Read the record line by line with your neurologist and do not read patterns alone. The diary study also calculated individual probabilities, which got more precise the more days were captured. It only included people with at least 90 days. That describes the study, not a rule for you.

In Sam you keep the same record in the program for migraine, which is a diary with a doctor report and a monthly questionnaire. Each attack is an entry with date, strength, duration and aura. Drink and the time of the last glass go in the note, which is not printed in the doctor report. Entries you make today show last night's sleep and HRV from Apple Health when those values exist. Symptoms without an attack go in the symptom diary, where you also mark drink days as yes or no. The program starts after you confirm that a doctor has diagnosed migraine. See how sleep and resting heart rate relate to migraine for what Apple Health data can add.

What do you ask your neurologist?

Take the record with you and ask, for example:

• Does the gap between drink and start fit a migraine attack or an alcohol headache?
• What should the record contain besides this, and for how long?
• Do sleep, stress or a missed meal on these days play a part?
• How do we handle alcohol while the pattern is unclear?

Whether you avoid alcohol, drink less or keep your habits is a decision with your treatment team. There is no recommendation in this guide. If your attacks tend to come on certain days, the post on migraine triggers: sleep, stress and tracking covers the other common causes.

Log your drink days and attacks in Sam and take the report to your appointment

You have attacks with times in one place, and you take them as a report to the appointment. The program for migraine is a diary with a doctor report and a monthly questionnaire.

• Instead of loose paper: entries you make today bring in last night's sleep and HRV from Apple Health, and you add the drink and the time of the last glass in the note.
• Instead of remembering in the appointment: the doctor report sums up the period you choose as a PDF.
• Instead of Apple Health alone: sleep and HRV sit there without your attacks; in Sam they are in the same app, a few taps from the entry.

Sam shows you what you entered and does not assign a trigger.
