temporomandibular joint disorde
"When my dentist first prescribed Valium for my TMJ, I was quite surprised. I had no idea of the correlation of TMJ and Valium.  In my case, the Valium works like a charm, I just take as needed when I feel my muscles tightening on me (which will inevitably lead to a TMJ-migraine).  The only downfall is that I have to wait until night to take it because it completely wipes me out into dreamland."
