Ok so I have had this "bug" hit me at least 17+ times over the last 3 years. One day I will be feeling fine and such and then, I get these burps. There terrible, they smell like sulfur rotten eggs. Its so bad I literally shake when ever it happens. The burps usually last a few hours then the vomiting takes place. And Thats well... you know how vomitting feels. I thought it was food i was eating, now i have stopped eating those foods. I've gone to the doctors and they did tests and they really didnt have an answer for me. Have you ever had this? This is terrible and i cant take it anymore!
