I have acid reflux, and had a sudden onset of reflux at work tonight (it usually happens while asleep and it is very infrequent of late). I take omeprazole daily, and had nachos with cheese, and a cheesy bean burrito for dinner, but six hours earlier. I then experienced very slight lower jaw pain, which has since subsided. I took an acid reducer a co-worker had, and some antacid tablets when I got home, and feel pretty good now, but was concerned about the sudden onset of the reflux.
