i have been on vyvanse 30 mg for about four months. i am a 19 year old college student who has suffered 9 concussions in a span of 5 years. i can't say for sure what they will do for me in the future, but right now i have never been more focused in school. last semester i got 3 D's, 1 C, and a B and this semester while taking vyvanse my grades are 1 A, 2 B+, C+. i have been able to concentrate on school for more than just ten minutes at a time and actually retain the information. I don't normally take the medication on the weekends to give me brain a break, i find the medication to be more effective this way. i'm a huge fan of it, but everyone is different. if you think it might be helpful then i think it's worth a try.
