I love learning things about my body, especially because I seem to know less than most people my age know about themselves.
Tidbit of the day: I suspected this before, but now that it's happened again, I can call it definite. Six hours after I have a dose of pseudoephedrine, not only can I start feeling my nose get stuffed up again, but I can start feeling my thoughts get unclouded again. That stuff really messes with my ability to think clearly and move at a normal speed.
But depending on how bad the cold is and how much thinking I have to do, it can still be worth it.
