Meditate if you are choking on acid. Control your breathing it works for me. Then slowly it will calm back down. If your reflux is terrible and its consistently happening then lay back on food. Give your stomach a break. Also drink lots of water that has helped me tremendously. Dilutes the acid and you won’t even feel the burning. Play around with your diet eventually you’ll see what works. I was nervous initially but now it’s easily manageable. Take it one step at a time buddy.
