Hi and welcome to the GERD forum.
Were u advised to modify ur diet and lifestyle in addition to taking the meds? It is important to do this to aid the meds...so u can get off the meds and get back to a natural balanced digestive track.

Did ur Dr do testing for this?....did he /she rule out a hiatal hernia?
Read the article in the link I attached for tips on how u can modify ur diet and lifestyle to help feel better.
