I turned on the T.V. - people were on it. Got a migraine.
I turned on the computer, surfed the net - people use these things too. Got a migraine.
I walked out my front door and the sheer volume of falsities and half truths escaping the lips of everyone I encountered helped to bring the onset of a migraine.
I read the Tao and took an Advil - migraine went away. Whoever invented Ibuprofen is God and consequently exempt from being judged an unworthy human being. Lao Tzu, go F yourself.
You also become sensitive to light and sound and feel like you're gonna puke. Even the slightest light is irritating. The best thing to do is just sit in a dark quiet room and fall asleep. Don't take pills because you will just throw them up. Most of the time a good sleep will get rid of the pain.
Most people experience one migraine per lifetime. But obviously it varies per person.
2.) "I have a migraine, fuck off."
3.) Like I said earlier, it is probably the most painful thing ever to experience.
