it just came all of a sudden few days ago. My nose is runny, I keep sneezing all day and i've been coughing every night. i've taken some meds yet I am still feeling under the weather. today i've boiled some chinese herbs meant for treating cough and pleghm. i hope my cough will be better after drinking it. with this hot weather, we must drink more fluids and i've been downing lots of herbal tea and barley water to cool my body.
