Brief Answer:
Not Advisable

Detailed Answer:
The active ingredient in zzzquil is diphenhydramine, a antihistaminic which has a sedation potential .

Trazodone is an antidepressant of the serotonin antagonist and reuptake inhibitor (SARI) class. It is a phenylpiperazine compound. Trazodone also has anti-anxiety (anxiolytic) and sleep-inducing (hypnotic) effects.

As both the agents have sleep inducing properties, I will advise you to stick to your prescription medicine of Trazodone , Combining two drugs with the same effect can lead to unpredictable response and undesirable side effects.

Thanks.

Please let me know if you need more information.
