Sorry to hear this waves, it is the time of year everyine gets sick.
Has the doctor given you any antibiotics or something tokeep it from turning intopluasy or pnumonia?
Anything OTC that has Gutussin (sp) Robotussin does, is helpful. Another thing the doc did for me because of my asthma, he perscribed a cough guffussin with albuterol in it.

If you have asthma, remember you may need to increase your meds when a bronchial inflamation is there.
I had to do my Advair three times a day and my albuteral when I had bronchitis in September.

Hoping your feel better soon.
