Nasal washes/rinses worked wonders for me. I don't have cf, so I take advil cold & sinus (Ibuprofen & sudafed) when I start to feel one coming on. Another thing I do is use doctor bronner's peppermint soap in the shower -- wash my face with it, put a hot washcloth over my face with some of the soap on it. Feels cooling.
Before I had my tonsils out 7 years ago, I also found that putting an icepack on my forehead would help.
