Is Trazadone The Right Medication For Insomnia?

my husband has been given trazadone for being unable to stay asleep but everything I read says it s for depression. He has Parkinson s and takes Carba/leva dopa, and another. I ve taken anti depressants for years so am familiar with many so am concerned about this med for him. I took it years ago and felt very sluggish so stopped. I take Cymbalta for dep and fibro now. I take Ambien for sleep which I consider to be much better but his PD Dr says it s addictive, yet my Dr told me it isn t tho I could become dependant so I take 1/2 tablet but not every night. Why do you think my husband s Dr preferred Trazadone. He doesn t need to feel sluggish as his med makes him sleepy in the afternoon already. At night he just can t stay asleep.
