I'd like to share my experience with acid reflux as it may save some of you a lot of pain and head scratching. Some 3 years ago, out of the blue, I started to get terrible heart burn, indigestion and the feeling of being bloated after eating. My diet was no different, the usual porridge in the morning, wholemeal bread sandwiches in the day and a meal with meat, spuds and 2 veg, a pasta dish or a curry at around 7PM. Then one day reflux descended on me. I couldn't sleep at night, had to lay propped up, and no amount of indigestion medication worked. I thought I had an ulcer or something and so did the GP when I visited. But after an endoscopy and ulcer ruled out. Long story short, I was put on Lansoprozale (a PPI) and that was it. Well the PPI only lessened the symptoms a little, and the problem persisted. Nothing I tried, be it acid cider vinegar, charcoal pills, or tinkering with my diet helped. Then I read a book that cracked it.
Out of desperation I bought a book by Dr Norman Roubillard, found out about the problem (Small Intestine Bacterial Overgrowth SIBO) and followed his suggestions. The problem didn't go away immediately, but very quickly the symptoms abated and within a week I was able to come of the PPI medication, which at this point I'd been taking for over a year. His premise is that most people with acid reflux have a diet that is heavy in carbohydrates and many of these foods ferment in the gut causing a gas build up that causes bloatedness, the feeling of wanting to burp but not being able to, and stomach acid to back up into the oesophagus. He lists foods according the their fermentation potential and if these are avoided the problem pretty much disappears. This was true for me.

Lots of information about the condition but I'd suggest getting his book. It got me out of a very dark place.
If you need to change your symptoms real quick, the paleo diet will also get you there in a couple of days. But I like my carbs, so mostly follow a selective carb diet.
