I had some nice self effects from TAF a couple of weeks ago. My gf was swamped with classes and I decided to help her out. I needed to read a couple of passages and do an essay, the first essay, I completed, the second I was half falling asleep by that point. When I began to read the topic and the passages, I couldn’t for the life of me concentrate. I was spacing out and I couldn’t get a full grasp of the content. Since it was really late, I decided to try and put some TAF on, I know it had some qualities that helped with my concentration.
Long story short, she picked one of the essays and essentially got the highest grade in the class. Good stuff.
