My whole family has problems with acid reflux. I had severe problems many years ago, had to raise the head of my bed up on bricks, and still have to use several pillows sometimes at night.

Mine was/is stress-related, and once I learned how to manage my stress, not to eat heavy meals too soon before going to bed, and to avoid the biggest triggers, it eventually subsided into a minor nuisance.

I still have to watch those things - stress, no heavy foods before lying down, and avoiding my triggers (like caffeine and heavily acidic foods) - or it comes back.

All three of my brothers have it, one takes prescription medication for it and the other relies on Gaviscon. The third was recently diagnosed with diabetes and Hodgkin's disease and had to alter his diet and that seems to have alleviated his acid reflux symptoms.

I think the two key culprits are stress and lying down too soon after eating.
