Since I was a teenager, I have noticed that when I'm hungry, I sneeze. This only happens when my stomach is very empty (like before breakfast). I will first notice a slightly nauseous feeling, followed by a huge sneeze, which is then followed by an immediate sense of relief. Nausea gone instantly, stomach not feeling empty.
When this sneezing occurs, it's usually 3 or 4 in quick succession, and these sneezes are huge!
I'd like to add that I have no allergies whatsoever. Since a young age, I also noticed that my father had "sneezing fits" every morning while he was on his way to work (he would eat breakfast near his office). My mother searched fruitlessly for a cause of the sneezing. When I told my father about the link I had found between my sneezing and my empty stomach, he pondered in silence. I think that he has found my explanation rather dubious. So, am I crazy, or is there a genuine link here?
