"i have been on add meds off and on for about 10 years. i&#039;m 33 and before vyvance i had tried concerta and adderrall. while the other two were ok, they did not benefit me nearly as much as vyvance. in one semester i went from making a 50 on a college algebra test to making a 100% on the comprehensive final. my professor said he had never seen anything like it, someone going from a 50 to 100. for the first time in my life i remembered to pay bills on time, i don&#039;t forget about the clothes in the washer for days, or forget to turn off the stove. i feel so much more accomplished!!"
