"my focus and energy increased immensely. i did a 4 to 6 page research final paper in 3 days. i finally can focus on tasks and not spend hours and hours on one task because i dosed off and daydream. i also did a 13 page ap english within 9 days. i&#039;m glad i decided to take adderall xr at the end of high school and now i will be taking it while i&#039;m in college. is it a cognitive enhancer which is said a lot absolutely not. it doesn&#039;t make you smarter, it doesn&#039;t improve your thinking, and it doesn&#039;t improve your memory. it just do what its suppose to do and helps you focus. the bad thing is that it is hard to sleep."
