I am so sorry you are ill during your last days home.
Know you would rather be bouncing around reveling in family/friends
FWIW - what you have seems almost epidemic here. And just lingers. There truly seems to be no difference for those who opt for Medcal care or self treat - so likely a virus. Just trying to curb nasty symptoms while the bodies immune system does its work is wise
We use the old honey & apple cider vinegar for coughs - mostly for mom as it has been decades since I have had a coughing situation.
Most of hers is phlegm/allergy related anyway but the combo seems to soothe & break up the mucus & I am sure rich in healing qualities.

Good Morning to the Dawn Patrol.
