sometimes after a cold i do the same thing.its gross but the thick mucus is like a sign the worst is over.it goes on for a couple of days then stops.but i was just diagnosed with sinusitis.i had a bad headache needed antibiotics.
if your mouth is dry try increasing your fluid intake and take some lozenges if your throat is sore.
Hi,
I had something very similar and the doctor prescribed me Mucinex DM. It was specifically for the hacking cough I had (day/night), which stemmed from drainage. It worked for me.
Hope you feel better!
