Puking

Have you ever been sick at work, I mean physically sick? I have. Luckily in the privacy of a toilet cubicle. I had eaten a kit kat a little too early in the morning, and had a thumping headache, and as I sat at my desk, amongst my healthy co-workers, I had to urge to puke. So I did. And now I feel a lot better. Sometimes I get really bad headaches, and they make me feel nauseous, and I inevitably puke, and then I feel better for a while. Why is that? Why does puking ease a bad headache? Maybe it’s just me. My head does work in very mysterious ways.
