Anyway, for me, whenever I have a headache, I drink coffee and then the headache is gone in a few minutes.
Are there any more common things that cures your headache, allergy or anything when you take it or drink it based on your own personal experiences? Just had to know, since when I tell people that, they say, "Nah, you're kidding."
Does coffee cure headaches in general?

never heard of coffee curing headaches : )
sleep or food, or lavender on the temples is good. a light head massage with the oil can help.
