After several years of having trouble falling asleep, staying asleep and also going back to sleep, due to the onset of tinnitus in 2020, I did a lot of research on brainwave activity and it’s positive effects on sleep. The Zeez Pebble looked the best product on the market and with their money back guarantee, I invested. I used to take up to an hour to fall asleep and would wake up 2-4 times a night, sometimes taking up to 30 minutes to fall back asleep when I did wake up. After using the pebble, within a week I was falling asleep faster (taking just 5-15 minutes maximum) and either staying asleep throughout, or maybe just waking up mainly just the once, or occasionally twice. Even then I would go back to sleep very quickly. It’s been a revelation for me and my partner, who has now invested in one herself. We use them every night, they are small, light and portable so can be easily taken on holiday, or whenever we are away from home. I highly recommend anyone who struggles with either getting to sleep, staying asleep, or getting back to sleep, to invest in the Pebble and use it every night for three months and see how you find it. I am happy to say it’s truly transformed my sleep for the better.
