After a whole month of every single day battleling with extreme out this world acid reflux and heartburn...after literally having acidic puke in my month 2 minutes after taking 2 tums.. after the hours every night of extreme chest pain caused by the extreme acid reflux and heartburn..after bottles of tums- chalk and chewable. After zantac 75 and 150.. after a month of crying and no sleep. ..and after a big A-OKAY from my obgyn, I started Prilocec OTC. It's been 3 days and I've been back to normal after day one. It's a life saver.
