Hi and welcome to the GERD forum.
May I ask did ur Dr inform u on how to modify ur diet and lifestyle? This is important to do along with meds, as meds alone can not help...u need to eat healthy and avoid the triggers...and u need to exercise even if that is going for a walk around the block every night at the same time.
Keep a journal of what u eat and do to see what ur triggers are.
For more tips on how to modify ur diet and lifestyle look at the health pages here on MedHelp -
