I have been told by my dad that swallowing bit and pieces of crushed ice does the cure as a natural home remedy for acid reflex and heart burn. Although my throat was burning like crazy, after being waken up twice in the middle of the night, I went to my refrigerator and filled up a cup of crushed ice. than I started to swallow a lot of crushed ice pieces. It took about 10 minutes and the acid in me was gone. I did not experience acid reflux that night again after swallowing a lot of crushed ice. Try it it will work. It cools down the burning and also makes the acid less concentrated in your body. Over-all the swallowing crushed ice method works. If anyone experiences heart burn or acid reflux, swallow crushed ice, it works! Attempt to swallow the ice at a reasonable size to avoid difficulty and discomfort of swallowing. But further more the best defense (in my opinion) is not to eat after 5 or 6 PM. The average person's metabolism slows down during night which can increase the chances of acid reflux or heartburn when you sleep. avoid late night eating, and boost up the metabolism by getting on some kind of exercise program. It can be as simple as walking around your neighborhood.
