Is Caffeine Good or Bad for a Migraine Headache?

Another thing is caffeine. What caffeine does is it does constrict your blood vessels. So if you don't have caffeine in your diet and you're having a migraine, your blood vessels are dilated, you can use a little bit of caffeine to help constrict them to help with the ease of pain. But if you have too much caffeine on a daily basis, your receptors on those blood vessels don't respond to the caffeine. So they basically become inactivated from too much caffeine. And what sometimes happens is you feel like you need more and more and more of caffeine to have the same effect. What I typically recommend for people who have are prone to migraine is that try to limit the amount of caffeine. So have one or one and a half caffeinated drinks at the most in your day. Trust me, don't do this. Don't just stop cold turkey because it's the worst headaches of your life. So gradually wean yourself off of caffeine. So what I typically tell my patients is if you have a lot, let's say you have like eight drinks a day, drop it by half a drink per week.
