Terry Y. reviewed Qualia Focus
It's a rare thing, getting up early with renewed energy, exercising, all with a keen sense of time and ability to avoid distractions. Focus seems to be working after just 2 weeks. I'll be continuing to take it.

If you are looking for a totally natural way to enhance your focus and concentration, I highly recommend Focus from NeuroHacker. I has totally helped my performance at work.
