Nexium
"I suffered severe pain from GERD that I had to be hospitalized. The next day I bought the Nexium 24hr, not because I saw it was the top selling brand at Walmart, but because my mom said to get Prilosec lol. Anyway, within minutes the pain from my GERD disappeared. One con I've had so far though. The medicine states 24hrs, for me it's roughly 18-20 hrs and I start feeling the acid again. So keep that in mind."
