Something weird happened to me today

I was driving to work and all of a sudden I start getting nauseous, it kept getting worse and worse and eventually I go “okay I need to pull over to throw up” so I try getting somewhere but I couldn’t hold it. I managed to hold it all in my mouth until I parked all fucked up and grabbed my trash bag. Then I proceeded to violently throw up the WATER I just drank and I threw up like 5 or 6 times. Then I magically felt completely fine. No bit of nausea or anything. And now I’m at work. I haven’t felt sick allll day lol I’m at a loss for what just happened
