ICK! Instant Nausea...

I'm experiencing this right now. Has this ever happened to you? Where suddenly, you're just overcome with the feeling to YAK?!?!?! I hate it. Some people get it to the point where their eyes begin watering.

It's the weirdest thing. I dunno what triggers it. Sometimes an odor. Sometimes a vision. Sometimes a sound. Sometimes...nothing at all. It usually disappears as quickly as it comes on. I've never puked from it. Just makes me sick overall.

This poor soul knows of what I speak
