Acid reflux

 I know a lot of women experience acid reflux, heartburn, or GERD when pregnant, however, im not pregnant - just hopng to get some advice from people who experience this.. I have GERD and it always hits me late at night when I'm trying to sleep and it lasts for a long time, and it's extreeeeeemely painful. Painful as in a lot of times I've been sent to the hospital because of it. I need some advice on dealing with extreme acid reflux or GERD; Such as what are some remedies to help it calm down, or things to eat. For example, I know milk can calm heartburn down a little. But I really need advice because the pain is unbearable sometimes.
