hello, Thak you for trusting HCM Metamucil will not cause acid reflux symptoms Here are few things you can try to relieve acid reflux Avoid spicy, fatty, and fried foods as well as chocolates and carbonated drinks. Avoid citrus-containing foods like tomatoes, oranges, and fruit juices. Eat multiple small portions of food rather than three large meals. Limit caffeine intake. Have your dinner at least two hours before bedtime, so that your stomach is light before you go to bed. Elevate the head end of the bed by placing wooden blocks under the bed post. Using extra pillows will not provide relief. Avoid cigarette smoking and alcohol consumption. Maintain a healthy weight. You can take omeprazole 20 mg daily in the morning before breakfast.
