insomnia
"I've been taking trazadone for about 4 years. I started because my mind would not settle down enough at night to allow me to go to sleep. Trazadone @50mg doesn't knock me out or make me so sleepy I can't stay awake but it absolutely settles my mind enough that I can lay down and sleep. 
Yes I'm a little groggy when I first open my eyes but within an hour I'm wide awake and looking forward to another nights sleep."
