I have been an insomniac all my life but don't like the adverse effects of most sleep aids. This was given as a gift to me. I would have never thought that something like this could work! I rub some on my temples and my lips and I slowly relax and fall asleep much more easily. Of course when I am completely wired it won't work as well or as fast, but I was amazed that on some nights that I forgot to use it I tossed and turned for while. Then I put this on and then fell asleep! I don't know how it works but it does. The smell is very discreet and pleasant.
