possible bloating relief

I usually don’t make posts on Reddit, but I really hope this method helps someone.
I’ve been suffering from chronic bloating for years. It has even gotten to the point where, on some days, I’ll begin a cycle of vomiting that usually doesn’t stop until I go to the ER. For years, I thought my stomach was simply big, but today I realized that a lot of its size was actually caused by trapped gas.
While I was lying down today, I started burping so much that I couldn’t fall asleep. I began rubbing my stomach in circular motions while pressing down kind of hard. That released a lot of gas, but out of frustration, I then started aggressively shaking my stomach from underneath, if that makes sense. I also twisted from side to side and continued massaging it.
I immediately started releasing some of the loudest burps in the world. Afterward, my stomach became completely flat.
I was extremely bloated, so the entire process took me around two hours of constantly massaging, twisting from side to side, and aggressively shaking my stomach.
Disclaimer: I’m sharing exactly what I personally did and what gave me relief—not recommending that anyone aggressively shake or press hard on their abdomen.
