I was given the Zeez pebble as a present from my husband for Christmas. I have a complicated relationship with sleep which started as a child and manifests in that I cannot drop off to sleep easily and even if I do I then wake up about 2 hours afterwards. Since using the Zeez I find that I do sleep more deeply and even if I wake up I can go back to sleep much more easily. I also have less anxiety about dropping off to sleep. I cannot say that my sleep is perfect but it is so much better now. The Zeez is a remarkable tool for relaxation and I think that over time my sleep will become even better and deeper.
