Echo burps smell like rotten milk, have an upset stomach , headache / dizziness, lack of appetite and diarrhea. What about me ?
Something you ate ? But it sounds terrible! Return to a soft diet for a few days . Let your stomach rest . Try to avoid gluten for a week or two to see if it helps. Reduce stressors . Try lactose-free milk , because the milk could be that is causing the discomfort.
