After trying lots if different remedies for heartburn and indigestion, I've finally found a cheap alternative to Gaviscon........love hearts!! They work do well and don't leave a horrible chalky taste in your mouth like some chewable tablets do. They contain sodium bicarbonate which is also in Gaviscon, the stuff that regulates acidity. Give it a try if you haven't already, so relieved they work perfectly and only 30p from Asda!!! Happy is not the word haha
