Everything smells like smoke

And everything tastes like chalk. I woke up this morning and, for the fifth time in as many days was unable to enjoy a cup of coffee. Do you know what that is like? I've drunk coffee every single morning of my adult life, darn near. To find that your absolutely favorite beverage on the face of the Earth (next to water) suddenly tastes like chalkboard dust is maddening. Is there any wonder I'm bitter and angry?
