This is an excellent product which does exactly what you want: it helps to give you a good night' sleep and feels natural rather than "drugged" - highly recommended

Occasionally, I cannot fall asleep. When it occurs, I take one pill. It is happy to see it does work!

too bad, I took this and I can't sleep

Posted by 4891567878600728214 on Jun 09, 2014

I took this product hope I could get some deep sleep, I want to sleep like my baby girl, but the truth is I can't sleep, I almost up all night, this is outrageous! I sleep a lot better before although I might wake up sometimes but I could always get to sleep again.

IT does knock you out... great night of sleep without drowsiness!!! excellent

Posted by Reviewer1761634 on Jan 31, 2014

I've been using Valerian to sleep for a while, but lately when I wake up during the night, I wasn't going to back to sleep very well ... so I'm trying something new... I don't like to use strong pharmaceuticals, which can make me really drowsy the next day and can be habit forming.... so I'd rather stick to naturals.... I've been using 'Knock-out' only for a week.... the sleep is wonderful, quick to sleep, if I wake up during the night, I quickly fall asleep again.... I'm getting traight 7 hours and could possibly get another 1-2 if I had the time.... Its highly recommended... the only caveat is that having melantonin you need to have 2-3 days off a week, so that your body doesn't stop making it and you always rely on supplements... excellent stuff...
