Vomiting instantly cures all hangover symptoms?

This is something that I realized a while ago and it has worked every time. What I used to do when I got a hangover was lie in bed feeling like absolute shit for hours. I would have a horrible headache, and nausea, but the nausea was normally not to the point of needing to vomit, so I wouldn’t. I would just lay there and wait it out.

Well one day I woke up with an awful hangover and I was like “fuck this nausea I’m going to go puke” so I went to the bathroom and stuck my fingers down my throat to induce vomiting until there was no more nausea. It got rid of my nausea as expected, but what surprised me was that my awful headache went away too a couple minutes later.

Now every time I wake up with a hangover I instantly just go to the bathroom and induce vomiting a few times and the hangover is gone in less than half an hour instead of several hours.

When I googled to see if other people do this, all I found was a bunch of people saying that vomiting will not eliminate hangover symptoms. But it literally has 100% success rate for me?? So what is going on here?
