Already experiencing a major difference having the Pocket IQube. The car show on Sunday was much more enjoyable – Protection setting on repeat. Did not feel drained or scattered. So far at work I am able to focus and concentrate on the task at hard – My tracked daily activities have even improved. I totally sleep like the dead with it…. LOL. I have played Magnesium Sulfate the last 2 nights and it has helped with the shoulder pain. Loving it! ; )
