In order to ameliorate the pain and discomfort of acid reflux, consider breaking your daily food intake into five or so smaller meals instead of three main ones. This helps prevent you from overloading your digestive system at any one time, making acids work more effectively in smaller amounts. You will soon start to notice a real change in your symptoms for the better.
There are certain foods that trigger acid reflux. Therefore, it's in your best interest to avoid these if possible. One example is chocolate. While dark chocolate doesn't appear to be as bad as high-fat milk chocolate, they both contain caffeine and cocoa, which are both known to cause acid reflux.
If you have been taking antacids over an extended period of time, chances are you have acid reflux. While it will not hurt you to take tums every now and then, continuing to take them when the problem may be more serious is a mistake. Go see a doctor if you have had symptoms for quite some time.
