I bought Zeez more or less 6 weeks ago. I'm extremely happy with the product and the results in improving my sleeping time quality. Before using Zeez I used to sleep 4/5 hours per night and then, after a couple of hours awake, eventually falling asleep again just few minutes before my wake up alarm. All this if I was lucky. The working day was then very hard to sustain in this constant tiredness conditions. Now everything changed and I'm very happy to use it also on business trip when I change bed every night. I recommend Zeez to everyone with sleeping problems like me.
