So, you still have a sinus infection? I'm really nervous about flying because that's how I first got the infection I'm dealing with now (I got it in Oct. and its now April, so the fun lasts for awhile). I'm really trying to deal with it before I move.
I'm also using a netti pot to flush stuff out and am putting grapefruit seed extract in it, which is supposed to kill fungus and is also a natual antibiotic. Seems to work. I'm finally beginning to blow stuff out.
