So, I'm very encouraged by all this - but I'm still a little uncertain about how to proceed.

I can get the saline solution up into my nose and it runs down my throat and I can even get it into one nostril and have it run out of the other by tipping my head sideways, but I can't think how to get it up into my sinus cavities too.
Is it just a case of lying on your back and pouring the stuff up your nose? I read somewhere that you can feel the liquid filling up your cavities but all I can feel is it running out....I think I'm doing something wrong?
