Basically if I eat stuff that digests slowly (fats and red meat), it takes my stomach a LONG time to actually break it down and move it forward. If I shove more stuff in there before it's done -> bad time.

I lost over 10kg during the worst episodes in about 9 months, I lived pretty much on rooibos tea (even green tea irritated my reflux), white rice and mildly flavored chicken.
