For that matter, I've been trying to find shampoo and conditioner that work well on my hair and don't give me a headache for a couple of years now. (Fortunately, my tolerance for scents seems to have increased somewhat in the last year or so, since there just isn't any unscented stuff available anymore.)

My roommate, back in college days, went into too much smoking and decided to quit. It was springtime, and he started sensing all the smells - flowers, fresh air, everything. His nose literally woke up, and he could sense a garbage can half a block away. After two weeks, he reverted. He just couldn't stand the odors, and began to smoke again just to anesthetize his olfactory perceptors.
