gets my kid to sleep

Posted by LauraLeonard on Jul 08, 2016

My teenager developed sleep issues. To me he seemed as though he was sleeping all of the time, however he said he was Resting. Anyway he is t sleeping all of the time any more and says he's well rested.

Best sleep ever!

Posted by 5281158051226693988 on May 30, 2016

I've taken prescription sleep meds for years and just couldn't take the side effects any longer. I saw this product and decided to try it. This is probably my 4th bottle of it and I am having the best sleep ever with it. This doesn't have the side effects of RX sleep meds such as headaches and weight gain. Kavinace gives me much deeper sleep and helps you fall asleep quickly. It is expensive but is still way cheaper than prescription meds and my sleep is so much better I will never switch back.

Not effective for me

Posted by Reviewer2884447 on Apr 15, 2016

Taking Kavinace does not have a consistent effect on my sleep. Sometimes I sleep fine without taking anything, but I struggle with insomnia and never know if it will be a sleep challenged night or a good sleep night. When I have taken Kavinace, I sometimes sleep fine and sometimes not at all. I have not seen any consistent benefit from taking Kaviance. I'm glad that it seems to work for so many other reviewers, but it is definitely not a one size fits all sleep remedy.
