I have had the same symptoms as all of you for 7 months. Coughing until I dry heave, constant super thick snot running down the back of my throat. 2 rounds of antibiotics and steroids without much relief. One day our cook at work made me lemon and grapefruit peel tea. I drank the awful cup full. I know it sounds weird but all the snot and phlegm was 99% gone the next morning and has been gone since. Trust me the awful taste is well worth the relief. I have continued to drink at least a cup full of the tea a day. It is still gone! I hope this will help someone out there.
