anxiety
"I'm 36, have social anxiety, GAD, TMJ, fibromyalgia, muscle spasms, cluster headaches, & herniated vertebrae.  I've taken everything, including 12 years on a high dose of Xanax. After finally convincing a doc to prescribe me Valium, I felt like a different person. It kicks in FAST, but Its long half-life prevents that awful anxiety rebound effect. I find that Valium has a powerful (yet feels gentle) calmative effect on the body as well- which is absolutely wonderful when my muscles & joints are tight. Valium is hands down the best benzo anti-anxiety medication out there."
