If taking citalopram 20mg and 5mg diazepam....for 7 months....can it lead to poor sleep quality?

Great Question!: Citalopram is a good antidepressant. Sometimes patients experience insomnia due to the stimulating effect of their medicine. Another possibility is an under-treated or partial response to your medicine resulting in your poor sleep. Also, diazepam can trigger a rebound insomnia. You will want to talk to your doctor to sort out what is going on that is causing you to have poor sleep quality.
