temporomandibular joint disorde
"Starting taking Valium for nightmares.  Yes, it stopped the nightmares, but the next morning was the first time I didn't wake up with a headache in 36 years.  I clench my teeth at night, so they pulled ALL my top teeth out and all but 9 bottom teeth out 12 years ago.  I still woke up with a headache every day.  Now, to learn that all I needed was a little Valium for 36 years!  I have 9 teeth left! The Valium works wonders, take my word for it."
