I had the opportunity to try Britefocus . After a 6 hour stressful lecture followed by a 1 hour exam, I am pleased to say the result was an outstanding success. Score 93%!
Anyway, I did feel so much more alert than normal. I worked to 9.30pm the night before and had to be awake by 5am the next morning for a 7am start. I sat through a 6 hour lecture with minimal sleep yet I felt that I had a full night of sleep. Directly after lecture I sat a 1 hour examination. Amazing result, AMAZING Product
