Hi VKat2016.
Thank you for your contribution and being part of the Migraine.com discussion forum!
For some of us as little as 1/4 cup of caffeine can contribute to making our head pain worse. In a small subset of people with migraine caffeine can also create medication overuse headache, moh or rebound. Caffeine is a drug, a stimulant, and for some of us can create moh. Here is a very good article about caffeine and migraine; http://www.achenet.org/resources/caffeine_and_migraine/.
Does that help?
