Omeprazole
"I didn't know I had GERD as I've never experience heartburn.  I did, however, experience difficulty swallowing and I constantly had to clear my throat.  I couldn't get a sentence out without making this annoying noise.  I thought I had post nasal drip, I was taking Claritin D every day (I stopped) and Flonase.  My Primary sent me to an ENT, I complained about this throat thing forever. After listening to me talk and hearing the hoarseness in my voice the ENT  said; "I don't think you have post nasal drip" put the camera through my nose and down my throat - I have Gerd... say whaa. I had no symptoms of that, so I thought.  That day I started taking 40 mg of OMEPRAZOLE... It has changed my life... almost immediately it went 90% away. :-)"
