OKay so I might not write a novel in one night but, man.
I have used this before and my brain really absorbs it. It works right away. I run my own company and have been very busy lately, juggling 10 clients at once. I am constantly multi-tasking. I get over 200 emails a day maybe more. No problem. The nature of my work is graphic design / digital media with a ton of writing and project management.
If you have a problem with brain fog, this takes it away. Gone. Clear skies and clear thinking which makes it effortless to come up with and execute great work.
So yeah I kinda love it.
I am able to switch gears from project to project faster though, which I was struggling with before.
I completely recommend it. I don't feel addicted to it. The days I don't take it are not dramatic or do I see a dip in mood or creativity.
But when I am in the zone -- I can stay there much longer.
I notice a difference in the quality of my work and my ability to integrate a lot of information and cut through the noise and come up with really clear concepts. LOVE.
