"im a 19 year old male. i struggled through school my whole life but still tested past most my classmates. i was diagnosed with adhd last year and was on a different medication that really didn&#039;t work and then a month ago my doctor prescribed vyvanse and it has changed my life so much. i recommend that every person with  adhd try it out. its amazing. the only real side effect i have is i&#039;m a little more irritable."
