Amazing product
I have used this for just over a week and I saw a change in my sleep the first night! The first night right after taking it I feel asleep with in fifteen minuets and slept almost all night I had two wake periods for no longer then six minuets a piece out of the entire eight hours of sleep. The second night I only had one wake period for only three minuets out of eight hours of sleep. From the third night on I have yet to have any wake periods and I am now in four to six hours of deep sleep! I am finding through out the day I can focus and retain information a lot easier then I could have before taking Masterbrain.
