Vital to breathe steam. Steam inhalations - boiling water, big bowl, breathe it in, towel on head can be done, and drops of eucalyptus oil make it even better. Breaks up crap in lungs and opens bronchial passages. Can be done a few times a day, have tissue paper (we use toilet paper...) to cough crap into because you will cough/hack/blow out stuff.
Great minds. I did the steamed towel thing last night and drank hot chicken broth. Both helped, so I will repeat several times today.
