Suggest Treatment For Cough And Acid Reflux

Ok I have had a cough for about 10 years... I use to clean houses and used alot of cleaning products... I have been to many doctors and they seem to think its acid reflux and sinusitus... I take 40 miligram of acid reflux each morning and it doesn't help... I still get to coughing and it takes my breath away... What do you think??
