Buy some pepcid complete or cheaper would be tums and a generic acid reducer (same thing). I get this all the time, iv eliminated coffee from my life and try to stay away from drinking too much. I still have a bit every now and then but its much less. Also over doing it on the antacids can make your body produce more acid on occasion since it thinks it doesn't have enough.
I didn't read the whole thread sorry if I repeated anyone. Oh and exercise.
