I start using Zeez nearly a month now. I have been sceptical how a device can help with my sleep that has been so difficult since I Was diagnosed with fibromyalgia. I have seen a significant improvement on my sleeping habits since I started using it which really surprised me and I can’t think now sleeping without it! I fall asleep quickly (less that 20’ from the minute I lie in bed), I fall asleep very quickly when I wake up middle of the night (worse case scenario). I used to wake up many times during the night but now I wake up one time and this is maybe once per week. I don’t wake up tired as I used to even when I have 6 hours sleep. I have checked all the above with my health watch too! I really believe this is an amazing sleeping aid device.
