I recommend a netty pot to rinse your sinuses. I have pretty bad allergies and that had allowed me to peel back 2 meds of my regimen.
My husband uses his for congestion and colds. I don't use straight tap water for this. I boil it it the micro wave and let it cool to decrease the miniscule chance of amebiasis.
Good luck
I took mucinex for 5 days and that helped me... but I took it every 24 hrs not 12 as directed. .. hope u feelbetter. ..
