Brief Answer:
Maximun 2 days.

Detailed Answer:
Hi,

I went through the query and understood your concern.

The active content in zzzquil is diphenhydramine whose elimination half live varies and hence complete elimination of the drug from the body takes around 36 hours to 45 hours (up to 2 days) maximum. But its effects will start reducing after4-5 hours.

I hope this information helps you and answered your question. Feel free to ask for any further queries. I will be glad to answer them.

Wish you good health.
Regards
