I was told acid reflux causing my constant cough,I was coughing constantly,I had throat scope and was told reflux causing cough,was given Omaprazale and gavescon,I have to take one impressive daily for 3 months.I'm only on Thurs day of taking.one in morning .I was a bit sceptical but I honestly can say it's really helped calm cough down.I'm glad as I was coughing most of the days prior to this constantly,it was exhausting.perhaps this will be helpful to those with constant cough.
