I have been fighting this for over two years. Now on Pulmacort inhaler 2x morning 2x night. Use in morning helps in clearing lungs of thick mucus. Also on Montelukast sodium night only and Fluticasone nasal spray 3x morning only. Thus combination has provided about a 50% ease of symptoms. Also drinking lots of water. Have tried Claritin and non steroid Nasalcrom prior to the above combination with no positive effect. Good luck to you!
