Heartburn can be a real bummer. Fast acting liquid treatments such as alchoseltzer work very very well, and can often relieve heartburn with a loud burp. Another remedy is a teaspoon of baking soda in a coffee mug of water, stirred, and slurped down. For persistent heartburn, an OTC drug known as Omniprozal, or it’s name brand partner Prilosec work very very well, but can take up to two days to begin working, and must be taken daily. Always consult your doctor before beginning any kind of drug regimen.
