If you're going to try drinking apple cider vinegar, make sure you brush your teeth afterwards. According to information I've read, the vinegar can damage tooth enamel over time. For more info: Apple Cider Vinegar.

Some other suggestions for GERD (Gastro-Esophageal Reflux Disease or Acid Reflux) are:

Drinking Chamomile, Ginger or Licorice root tea as a digestive aid.

Take Food Enzymes or other full-spectrum digestive enzyme supplement with meals (digestive enzyme difficiency can cause GERD)

Take Gastro Health to destroy Helicobacter pylori (H. pylori) bacteria that is linked to ulcers and other digestive problems

Eat smaller meals more often and do not drink ice-cold beverages before or during a meal. Avoid citrus fruit, chocolate, milk, soft drinks, coffee and alcohol.

For quick relief and digestive help, I've had several people swear by Stomach Comfort. These are chewable tablets with no aluminum, preservatives or artificial ingredients, and they don't have that "chalky" taste. What's really good (and different from other antacids) is they DO contain digestive aids like ginger, licorice and papaya fruit.
