I have had insomnia for a long time. Little helped. Now I have used the Zeez Pebble for three months. Together with the intake of magnesium and vitamin-B complex, my sleep quality has improved significantly since then. The CEO of Zeez, Anna Mckay, was very supportive and gave me excellent advice on supplements. I missed the magnesium and it helps together with the Zeez to sleep much better. There are still days when I don't sleep so well, but for me the difference is clear, and thus the investment in the Zeez was more than worth it for me. I can only recommend you to give it a try! Thank you so much, Anna!
