Also follow some lifestyle measures: Steam inhalation. Avoid following specific foods: Eggs,Fish and shellfish,Meat and poultry,Dairy and chocolate,Alcohol,Salt and these surprisingly high-salt foods,White bread, white pasta, white rice,Cakes and pastries,Coffee and sodas,etc which increase mucus production.
