I get that way but I think mine is more do to my hiatal hernia. Basically my stomach doesn't have anything holding it in place and the entire stomach goes into my esophagus. But ant-acids might help you.
No i get that way also, it helps me by straightening my posture to burp. Sometimes with the puking, i feel like i need to puke but i cant, and my stomach and chest hurt so much i will pretend to throw up and that will get me to puke more and then i feel 10000 times better.
