Add me to the list too, After 20 years in jetliners I seem to get a serious sinus infection at this time of year every year, after reading Loose's post about state of mind and sinus problems, I realize that I'm due for a check-ride and a Class one physical pretty much in the same month. I don't know if they are related, but seems to make sense, I too use a saline solution and it does help me breathe better. BTW exercise seems to move the stuff around and out too. Very interesting reading...
