Just wonderful watching "potential association between migraines and caffeine" become "THREE CUPS OF COFFEE A DAY WILL GIVE YOU MIGRAINES"pic.twitter.com/Ngl9oW6lsj
Oh, also, this was a study in migraine sufferers - it's not that caffeine will give you migraines, it's that it might trigger them in people who are susceptible
Absolutely! One type of migraine I get makes me crave coffee and I’ll drink three cups before breakfast.
Was it all self-reported? (Both intake and symptoms)
Thank you for your interest. As stated in our methods, this was a comparison of within-person changes in daily caffeine intake and day to day changes in headache risk, which rules out between person confounding.
