"I was prescribed this by my doctor and it was terrible. I stopped taking it after 5 days because my doctor told me to. It made me angry all the time. It did not help my concentration. Also, 3 days after taking it I still have shortness of breathe, my heart is still beating hard, and the left part of my chest has immense pressure on it. I'm never taking this stuff again. Trust me, nobody needs it."
