insomnia
"My psych prescribed trazadone 50 mg when I first started seeing her.  I took it one time and still didn't sleep so I tossed it.  A few nights ago I was so frustrated because I  hadn't slept for days so I tore the medicine cabinet apart looking for anything that would make me sleep.  I found the trazadone.  I took one and bam I was out like a light for 8 hours.  Guess I will give it another shot now!"
