this is really weird to me. i don't know if it's heartburn or acid reflux but yesterday i ate at 10am and then didn't eat again until 7pm and i got this really bad burning sensation in my throat that makes me want to throw up half the time & in my chest i feel hungry. this happens before and after I'll eat something. & now i just woke up, & i feel it again. i don't get it. i thought heart burn was after you ate something spicy? I'll drink water or something cold & it'll just get worse. 😖
