Chew your food
I've blamed my acid reflux on a few things (antibiotics, stress) but after talking to others who have the same thing there was another thing we all had in common. All of us rarely chewed our food, we all rushed or ate in big giant bites. When my reflux started (it started slowly with just belching) I was having a tooth problem that caused me to eat on only one side for about 4 months. Therefore I swallowed my food in big chunks. I'm sure this contributed to overloading my stomach and causing reflux. In fact the first time my reflux came up into my mouth I ate a giant meal that I chewed very little before swallowing. So chew your food. I think our reflux is caused by a digestion problem. My reflux only comes at night when I sleep, I also notice I have a ton of gas in my stomach when I sleep so I figure it's pushing up on my stomach and actually shooting the acid up into my throat (that would explain the acid defying gravity since I sleep on an incline).
An example is I ate chicken noodle soup yesterday, the noodles are known to be hard to digest (in fact it says it on package). My side, below my right rib was really hurting afterward (and no it's not GB, I don't have one). I'll bet one type of food is really causing my reflux from going away, I just can't find which one it is and everytime I try an elimination diet I can't stay on it for a day or two.
