wander to the nearest chinese medical hall, look at the section
where they have prepacked stuff for sale..
get one of those "Flu Tea" stuff... i use the stuff from this brand
called Chun Chun..
buy a few packets.. brew it with boiling water... follow the
instructions, there are english instructions on it (albeit
sometimes broken english but you know what to do)
smells like toxic waste and tastes worse... but it'll help with the
symptoms..
