After a nasty push-bike accident just over two years ago, my sleep pattern changed from having no sleep problem at all to waking up every 1 1/2 to 2 hours. Not only that, it could take me up to an hour to get back to sleep. I read loads of books on sleeping, what to do and what not to do. Tried changing my diet, taking certain vitamins that are supposed to aid sleep. Nothing worked! My husband was reading the paper one morning and saw an article on sleeping aids/suggestions. The zeez pebble caught his attention, and the explanation of how it worked made perfect sense. I read the article myself and decided to send for one and give it a go, nothing to lose! I Found it very easy to use and was pleasantly surprised, shocked even that it had made a difference. Do I still wake up during the night? Yes I do... but a lot less than I did, and the biggest change/improvement for me is the massively reduced time it takes to get back to sleep, maximum of 5-10 minutes. Would I recommend it? Yes I would, it isn’t cheap but it’s not expensive I feel, and you can send it back within the month if it doesn’t work and get most of your money back.
