I started using the Zeez pebble because I was a terrible sleeper. It is absolutely amazing! My husband told me he saw the pebble on TV and suggested I try it. I said “really? A plastic pebble”? I was at the end of my tether, the tragic events in my family made it even worse and I hadn’t slept properly in 3 years. I bought it, then didn’t use it immediately, but when I did try it I slept like a log for the first time in 3 years and woke up with a massive headache, like a hangover the first morning. I have used it ever since. Twice I forgot to use it and didn’t sleep well those two nights, reading again half the night. As soon as I used it I slept well again. I followed all the instructions, even moved the wifi extender out of the room. A stress rash I could not get rid of for months on end has also cleared up. It is unbelievable but it is true. I am feeling calmer because I can sleep and I am no longer a nervous wreck. I can’t tell you how much it's helping…I have mentioned it to friends who think I am crazy! I didn’t believe it when my husband first mentioned it, but it has become part of my life. It’s under my pillow every night and I have come to rely on it.
