Did u get lapband surgery? If so its this thing called PB, productive burping yet with out the burping. It means u need to basically spit it up, i normally called it throwing up but its soo not the same thing. It felt like pressure right? I cant stand it, if u did get lapband surgery this is why n it willl happen quit a bit, just chew n eat slower. But if u didnt have lapband then i just talked to myself lol.
