Pill Paranoia

Sometimes I think I know too much for my own good. I'm generally paranoid, and I do asinine things sometimes because of it. Case in point, I know that ibuprofen (Motrin) is metabolized by your kidneys, and that acetaminophen (Tylenol) is metabolized by your liver. So if I go too long using one of them, I feel like I am putting a strain on my kidneys/liver, and will avoid taking anything for my headaches, muscle aches, asshole aches, etc, until I can get the other one.
