thanks so much for your response but ironically i consume little to NO dairy
once every 2 weeks or so i have a bowl or cereal and its never happened when i consume the milk. i HATE milk so i never drink it yogurt i eat once in a blue moon cheese i dislike so its not dairy. everytime i get the burps i think of what i may have eaten and not one of those times i have consumed dairy in fact the foods that may have triggered it i eat again to see if its that and it never is! oh well i guess there may be no answer to this.
