Rated 4 out of 5 by from Works for me I decided to try this product because other reviews mentioned that it did not leave you groggy in the morning, which had sometimes been a problem for me. This does indeed seem to do the job without making one groggy. I do not use this type of product daily but sometimes need something to help predispose my mind to allow sleep.

Rated 5 out of 5 by from sleep easy restful sleep on a regular cycle WITHOUT the stink of valerian. The only improvement could be a slightly quicker tablet disintegration time.

Rated 5 out of 5 by from Really Works! I bought these for my husband and they worked so well for him that I got a bottle for a friend who was having trouble sleeping. She could go to sleep, but couldn't stay asleep. She says that this really does the trick for her. She had tried something from GNC that did not work at all, but she LOVES this product. My husband's problem was that he could not fall asleep and they work for this problem, as well. All in all, a very good product at a very good price. I highly recommend Knock Out!

Rated 2 out of 5 by from Not for me Perhaps this product would be effective for people with mild and/or temporary sleep issues but it did absolutely nothing for me. Nothing against the product really, just not something I would purchase again or recommend to anyone with real trouble sleeping.
