sedation
"I have been on trazodone for about five years, ever since I was going through a nasty downward spiral due to my personal situation at the time and couldn't sleep for three days/nights in a row. 

The doctor who prescribed it for me was an "old-time" doc who wasn't into unnecessary medication (or any, most of the time) but saw there was a need that day with me. The fact that it was also an antidepressant was also a plus (but ultimately it wasn't effective enough on its own for that purpose). 

Taking trazodone at night (50mg) plus 1/2 a typical Ambien pill helps me sleep a good five or six hours straight--beats the way I used to sleep and thought was normal for most of my life; waking up every two or three hours."
