Found this neato little list of tricks to clear your sinuses (it works), and various other things.

Here's one on how to get rid of a headache.

And this one's just kind of unintentionally comical. It burbles along kinda Zen-ning you out (by repeating the same concept a few different ways) then says, "Don’t worry about about [sic] your personality. You don’t really have one." See "how to get red of a headache" directly above.
