get somebody to punch you in the nose and watch the snot flow out (of course, there may also be blood, but it's a sacrifice im sure you're willing to make) :bigsmile:
but seriously, im fairly sinus-clogged all the time :p i just deal with it, but when it gets really bad (like yours) all you can do is wait it out, there's no cure for the most common of all diseases...how ironic...anywho, things like humidifiers, etc. can help, as everybody else has suggested, hot beverages, spicy foods and also, you can get this inhalent stuff (similar to the humidifiers' inhalent) and you just boil some water and mix them together in a mug or something and you can drape a towel over your head and the cup and lean over it while inhaling...it can help a lot...
alternatively (instead of the towel), you can get a paper bag and cut off one of the bottom corners and put that upside down over the mug, then put your mouth and nose in the hole to inhale...it can get really strong at times, but that's why it's so good at clearing your sinuses :)
