Last night, my parents brought home mexican food for dinner. After I ate a little bit, I was feeling very gassy and burping a lot. I took 2 Rolaids and it wasn't relieving the pain. And after I eat or drink, I occasionally vomit in my mouth after each burp. I do not have insurance to go to the doctor or ER, so I am asking for help to see if I need to go to the doctor or if there is another alternative.
