I have had this same problem and
recently found this site and
posted about my problem. I too cannot burp and
frequently get those little gurgles.. sometimes they are kinda loud and come up without me knowing about it. The only time that I do burp is when sometimes i get this coughing fit right befor
e i feel nausea and when I vomit i let out a burp that is so loud i have heard nothing like it befor
e. i often notice it after eating and a lot of times when i go out at night and drink alcohol.
