On the Subject of Head Colds

I hate head colds because it makes everything surreal and dreamlike. I'm not sure whether it's being sick or the meds, but it's like wading through a mental fog. Inevitably, when I go back to read what I've written, I spot all sorts of obvious errors. This is accentuated by reading a book on writing and language written by a copy editor. Now I'm scrutinizing my comma usage and trying to remember if I've ever seen the word "crotchet" used before to refer to anything but a yarn-based handicraft only to realize that what I'm thinking of is "crochet" with only one "t". Is there a word to describe the endless navelgazing of grammar paranoia? There should be. I think I use nausea vs. nauseate correctly and have you ever heard of a flat adverb before? I hadn't, but I sure am glad that I can now "Drive Safe" Arg! I need sleep.
