this really works

I was having problems sleeping. laying down with my eyes closed and telling myself as long as im laying here, I'm getting rest, along with other thoughts. Z Quill has ended that. I take a capful of this and I'm out, sleeping a full 8 hours. I usually take it about an hour b4 bedtime. I highly recommend this.

sleep-aid option for occasional use

The warming berry flavor is smoother than I expected, and the liquid format makes it easy to measure the labeled dose before bed. It contains diphenhydramine HCl, so it’s meant for occasional sleeplessness rather than regular nightly use. The biggest downside is that the taste may still be a little medicinal, and some people may feel groggy the next morning. Pros: Easy-to-measure liquid format Berry flavor is more pleasant than many liquid medicines Cons: Can leave some people feeling drowsy the next morning Not intended for frequent or long-term nightly use Follow the label directions and avoid combining it with other products containing diphenhydramine.

It works

I have trouble sleeping and have tried just about everything, but this product works. I don’t like taking liquid medicine. But this works so I’ll deal with the taste if it helps me to sleep.

relaxium absolutely worthless for me, but this product actually works. It helps me to fall asleep, and sleep for hours, which is very unusual for me. I spent most of my life as a professional driver, and rarely got any sleep. now that I'm retired this helps break that cycle

Helps me sleep!

This is the best thing I’ve used that helps me fall sleep without feeling groggy in the morning. Occasionally I have trouble going to sleep, and take about a 1/2 dose of ZzzQuil - within about a half hour I’m sleeping like a baby. Highly recommended if you have trouble sleeping!

A must for major insomnia!

I have diagnosed and medically treated insomnia and have had the majority of my adult life. The ZzzQuil nighttime sleep aid is the only over the counter brand that works for me. I've tried all other brands and types, even comparable brands and none of them will work for me. Only ZzzQuil. It comes in a small variety of different flavors, my favorite is the warming berry. It does not have that traditional medicine taste and is very easy to swallow. It is also very easy to use. They provide a pre-measured cup so you know exactly how much to take without risk over taking too much. I've been on prescribed sleep aids which I was not a fan of taking. The ZzzQuil is far more convenient and does not require a physician. Because it does contain 10% alcohol, it does have a really good child proof cap preventing little ones from being able to get in and drink it. The next morning I always wake fresh and not groggy at all. I love it so much I also started my husband on it as well. He now sleeps like a rock whereas he used to be a light sleeper, which is not good since I'm a night owl. I definitely recommend and we will forever be a customer.

I have chronic insomnia. Very difficult to get sleepy without requesting prescription sleep aids but HATE the side effects of the prescription stuff. Highly recommend this as a great alternative for those without sleep issues like pretty lousy insomnia issues 😴
