Lisdexamfetamine
"I have been taking Vyvanse 4mg for a month and my productivity in my work and school have increased measurably. I have taken several different ADHD medicines through a period of several years, and Vyvanse is by far the most effective. It hasn't caused me any of the side effects caused by most ADHD medicines (paranoia, restlessness, agitation, lack of appetite). Of course these are just my experiences, but I would recommend Vyvanse to others."
