Be careful at cocktail parties! Beer, red wine, sherry, and vermouth contain large amounts of tyramine, one of the most powerful migraine triggers. A bigger reason to steer clear of booze is that any type of alcohol
causes dehydration, which is a major cause of headaches
. If you’re drinking, it’s always a good idea to alternate alcoholic drinks with water or seltzer — but if alcohol is a trigger for your migraines, it’s best to refrain completely.
