70% of your immune system starts in your gut. How is your digestion? Have you eliminated both gluten and dairy from your diet? When I removed those two components I stopped getting colds and haven't been sick in over a year. Prior to my change of diet I used to get sick all the time.

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.
