When I have chocolate, the first bite almost always makes me sneeze! Then I don't sneeze on next bites. Why the heck would chocolate cause sneezing?

Chocosneeze syndrome. Just kidding, never heard of this. Maybe you are inhaling some powder from the bar into your nose before you eat, you are so anxious to get that wonderful chocolate high. It couldn't possibly be serious, so go ahead and enjoy. You can enjoy the sneeze too, just don't do it right on someone else! oh, and i wouldn't recommend chili flavored chocolate for you.
