Mike C. reviewed Qualia Focus
Give me my life back
Good for focus and productivity
Effects are subtle, but consistent. I'd describe them as a general increase in clarity and ease of focus for about 4-6 hours after taking before steadily winding down with no noticeable crash.
Qualia Focus
Focus helped me to start the day with clear head & energy to begin my day.
Focus without being wired
Not as much energy as with other products, but that is good in a way. Great focus, but doesn't keep you up so you also have to have a good sleep habit.
