insomnia
"I'm a 20 year old male and recently tore a muscle in my pelvic area, which radiated pain to my groin area as well. The pain worsened at night and caused me real bad restlessness and insomnia. Along with pain medication, Restoril (temazepam) was really a lifesaver. It does double duty by relaxing my muscle spasms AND relaxes my mind so I can sleep with my pain. It's gentle enough to take in the evening (you don't have to take it right when you get into bed, like Ambien). Causes no side effects for me, either. I wake up refreshed."
