yea my cold's been lasting for more than aweek. i mean there have been some days where i only about 6-7 hours of sleep during the time i've been having a cold but mostly i get about 9-11 hours of sleep. but i havne't been taking my medicine on schedule. the first three days when i first got the cold i just took this effervescent table that had alot of vitamin c and b vitamins together. then after those days i took dayquil during the day(two tablets)and at night nyquil(again two tablets. then the coupld of days after sometimes i wouldnt drink day quil and i would just drink wal-phed (which is a walgreens nasal decongestant) and at night i would nyquil. is this why my cold isn't stopping(my sore throat is almost gone and i have no cough it's just my stuffy nose that's not going away!)? cuz i don't take my medincine at a right and continuous schedule? but i thought our immune system is what kills the cold bacteria and the medicin is just something that suppreses the symtoms. and i'm not going to go to a doctor here in vietnam cuz all they'll do is prescribe me unknown medicine that doesn't even have a pamphlet describing side effects and ingredients.

SOME BODY HELP!
