Why do my eyes water and why do I sneeze after I eat ANYTHING!?

Hm, sounds like an allergic reaction, if its only happening when you sit around your computer, maybe something around that area is making you do this stuff, like dust, maybe try dusting your computer off? Or perhaps its the certain stuff that you eat that's making it happen. I'm not real sure, but I have the same problem, usually there's dust around and once I get rid of it, it gets better. :] Hope this helped
