I once vomited 33 times in a row.
The first 2 hits went into the toilets' sink.
I felt so incredibly bad that I was afraid of entering the kitchen to clean my hands because there are many huge knives and I really did consider stabbing myself with a knife to end the pain a valuable choice.
I got so scared so I ran to the shower instead and sat down for a while with some warm water running down my back to calm down.
Then I vomited again. More food came out, im reverse order to what I have eaten before.
I continued vomiting.
Now some white liquid, probably gastric acid, started to gush out my mouth (and nose) whenever I vomited.
After I puked around 15 times in total, I could feel how my stomach was already completely empty. Upon vomiting, I could feel the inner walls of my stomach crashing against each other, trying to press up some food that already wasn't there.
This continued for a while, and every single time I vomit it felt like there was a big dildo being rammed up my throat from the stomach.
Eventually I puked blood and THAT was the point when I started to be scared.
But after 33 times of vomiting in total, it suddenly stopped and only 30m later I could somehow sit and talk normally to my cousins again.
