I've never really thought about it, but today was my Birthday and my parents came over and we had a big meal. If I eat a LOT (enough to feel extremely full) I get sneeze attacks. Talking half a dozen or more in a row, and it makes my sinuses feel clogged, even though they aren't.
Apparently it's called Snatiation. And from what I gather it's not very common. It only triggers if I eat way too much, which seems to be easier for me now since I lost weight a simple overeating can lead to it. Where before it was only during Christmas or Thanksgiving dinners that I would trigger it. Like tonight's meal was a baked potato, some corn, and some fresh homemade chicken nuggets, made from chickens I personally raised/butchered (just to see how it was). Then a pudding dessert.
