The first day I used the product I felt incredibly alert and focused on my work. I was very impressed. Those effects seemed to diminish each day as the week went on though, as if there was a sort of tolerance at play.

5 stars

excellent, thanks

5 days on Focus. Day 4 began noticing minor differences. Craving for coffee or chocolate after lunch to stayed focused reduced....didn’t start that dragging feeling until late afternoon. Sleeping longer
