What kinds of foods are you eating? Some things cause me to burp a lot more (I think that is what you meant?)....for example, I had something with cucumber this morning, and even though I finished it over a half hour ago, I still have little burps coming up every few minutes....
Also, do you possibly swallow air? You may not realize it...and/or if you salivate and swallow that and it is bubbly - could be adding more air....there are so many things that could be contributing to your problem....
Hope it resolves soon.
