ADHD
"Got sick a good three times during the first week and felt dizzy. Continued to take it for another 2 weeks every morning but it made me drowsy to the point that I had to take a nap everyday. Switched to taking it at night before bed and could not sleep at all. On a positive note I did notice my concentration levels increased a bit but was surprised how I could read an article or a textbook and remember the information I had just read."
