We share your disappointment that this didn&#39;t help you get your rest, Debra. ZzzQuil, like many other over-the-counter sleep medicines, contains diphenhydramine HCI, an ingredient used to treat occasional sleeplessness. Our product is found to be safe and effective when used as directed, so we take a report such as yours very seriously. If your sleeplessness persists continuously, or for more than 2 weeks, we recommend you stop using ZzzQuil and consult a doctor. Your doctor, pharmacist, or sleep specialist can help you find the right sleep-aid for you. Your satisfaction matters to us, and we&#39;d like to gather a few details from you to further assist with this. Please give us a call at 1-877-881-5813 from 9AM — 6PM EST Monday – Friday.<br />
