Honestly, walking. You can use gas-x and stuff, but it only helps with the stomach gas. The rest of the gas that's trapped throughout your body, you just need to keep moving. The more you move, the faster it breaks up.
Also, I had someone pound on my back (gently, going up and down both sides of my spine from shoulder to hip) to help break it up, too.
It sucks, but hang in there. You can get through it. ❤️
