If you have a burning sensation in your chest two or more days a week, you may be one of 50 million people who suffer from frequent heartburn. Talk to your doctor, and most likely you’ll find that Prilosec OTC is a great solution. Prilosec OTC works for 24 hours with one pill a day to target the acid that causes heartburn by directly shutting down many active acid pumps. Prilosec OTC works all day and all night with one pill a day. Not many OTC heartburn medications work like that. Visit the Walmart website to request your free sample. CLICK HERE!
