Just a quick note because i was in this position a couple of weeks back, coughing myself to sleep, was told by the pharmacist and i quote "you're stuffed", i would suggest using eucalyptus extract mixed with boiling water in a bowl, and drape a towel over your head while breathing in the steam, also try wearing a scarf. Those two things fixed me up in a jiffy, and the best part is your not ingesting anything so doesn't effect the diet in the slightest.
