"i&#039;m a full-time college student in my mid-20s. i&#039;ve been on adderall for 3 months now. i cut my 15mg ir in half and take it in the morning and the other half 3 hours later (and another half after 3-4 hours if needed). i don&#039;t take it everyday, i probably only take it 4x a week. if you don&#039;t have an addictive personality, you won&#039;t be addicted to it. i have to say it works really well with my add. i&#039;m able to study for hours at a time. i don&#039;t necessarily think it makes you smarter. it just lets you focus on a task without getting distracted. i think my only complaint is sudden mood swings and agitation. i definitely noticed a difference in my personality the days i&#039;m not on it. i get angry very easily and irritable."
