I had chronic sinusitus, ear pressure, and a lot of congestion overall for months at a time, I thought it was just long lasting seasonal allergies. I stopped eating all gluten and dairy and the problems never came back since the source of inflammation was gone. I also use a neti pot daily to irrigate my sinus cavity.

People say I am on a "crazy" diet. What is so crazy about eating veggies, fruits, seafood and organ meats? Just because I don't eat whole wheat and processed food doesn't make my diet "crazy". Maybe everyone else with a SAD are the "crazy" ones for putting that junk in their system.
