"i was diagnosed with adhd, this year, at age 20 as a sophomore in college.  vyvanse is the first and only medication i have ever taken to treat my adhd. pre vyvanse, i had a cumulative 3.5 gpa in my first two semesters of college.  post vyvanse after 1 semester of taking it, i got a 3.62 gpa. while my gpa didn&#039;t increase tremendously, i did notice that i could pay attention in class a lot better and that i was learning a lot more. on vyvanse, i can easily put 12 hours in the library if needed and be way more organized. i recently obtained an internship for xmas break, and i wouldn&#039;t be able to work 60+ hours behind a desk per week without it. vyvanse has made a difference in my life."
