So i have been feeling fine most of the day. I went out to eat a late lunch with my friend. Everything was fine, we ate around 330p I went shopping at the mall, then picked up my car from the dealership, then went to walmart with my guys. Came home from walmart, feeling pretty good, then while i was wrapping presents I burped and it had an acidic taste and smell to it. So of course then my stomach got queasy, and now i feel like crap. Am I sick? Was it just because i was hunched over wrapping gifts? Could it have been reflux or indigestion? I am not panicked yet but i am heading that way! Please help!
