Thanks friggy. I will be sure to give this one a try.
Had the same problem, and fixed it. The infection is in the upper sinuses, where nasal sprays won't reach due to gravity, and antibiotics don't reach due to a lack of blood supply.
As the comments will verify, this works very well for your diagnosis.

Same things as the rest of us? Sinus rinses, humidifier, raising the head of your bed, and smiling when you want to bash your head into a wall because of the pain? lol
Seriously though, other than the aforementioned or surgery, there isn't a whole lot that can be done...except all the nasty steroids and such.
Try the Alternative therapies forum...they have some great ideas.
