What are some healthy habits to help control acid reflux?

There are a many simple lifestyle changes you can make to control acid reflux:
•    Elevate the head of your bed at least six inches. If possible, put wooden blocks under the legs at the head of the bed. Or, use a solid foam wedge under the head portion of the mattress. 
•    Avoid foods that cause the valve between the stomach and esophagus to relax during their digestion, such as coffee, chocolate, fatty foods, peppermint and spearmint.
•    Limit acidic foods that make the irritation worse when they are regurgitated. These include citrus fruits and tomatoes.
•    Avoid carbonated beverages. Burps of gas force the esophageal sphincter to open and can promote reflux.
•    Eat smaller, more frequent meals.
•    Do not lie down after eating.
•    Do not eat during the three to four hours before you go to bed.
•    If you smoke, quit.
•    Lose weight if you are obese. Obesity can make it harder for the esophageal sphincter to stay closed.
•    Avoid wearing tight-fitting garments. Increased pressure on the abdomen can open the esophageal sphincter.
•    Use lozenges or gum to keep producing saliva.
