Does this make you want to vomit?

Perusing some common grammar mistakes this morning, (like any normal human being, right?), I realized the frequency that I've told people I induce nausea. I am highly embarrassed that it's taken this long for me to realize my mistake. Henceforth, here's to always being nauseated and never being nauseous! errrm...

And now I'm freaking out that I might have misused "that" where a "which" should be. GrAmMaRpArAnOiA!!!!!!
