"i am a college student and i have to say this is by far the best adhd medication i have taken. i was taking adderall xr prior and was having major anxiety attacks/mood swings and just never really adjusted to it, so my doctor switched me to concerta. it has helped me tremendously, i am finding it so much easier to focus and complete tasks, i have gone from c&#039;s to the deans list over the last year. i feel no side effects, i take the extended release medication early in the morning so it lasts all day but does not interfere with my sleep patterns. i would recommend this medication, it has worked wonders for me!"
