### ⭐⭐ Review
*by H***G on 5 November 2024*

I was taking this for several weeks now to try to improve my focus for studying, and it was doing the total opposite. Whenever i drink this I can't focus or even grasp the most basic concept. It also screwed up my memory and gave me lots of severe headaches and sleep problems. It also tastes horrible compared to diet coke or other diet drinks.
