While we're glad that we've been able to help you get a good night's sleep, Rick, you certainly shouldn't wake up groggy and moody. It may be helpful to know that there are many factors that could influence how rested you feel, such as the number of hours you sleep and the time that you take ZzzQuil; we always recommend that you take ZzzQuil when you have adequate time to get a full night's sleep. That being said, all of our products undergo thorough testing before they find their way to your home, so this isn't what we'd expect from our Nighttime Sleep-Aid liquid. Because of this, we recommend that you discontinue using that bottle immediately. Your health and safety are our highest concerns, so our Safety team would like to learn more about your experience and that bottle you used so we can try to help further. Please give us a call at (877) 881-5813.
