"i have struggled with add since i was in grade school. although diagnosed, my mother was not about putting me on medication. that being said i struggled really bad until i graduated. i am now 22 &amp; have been out on almost any add/adhd medication you can think of. to keep it short &amp; sweet, concerta &amp; focalin worked for about an hour then i turned into a horrible person to be around - extreme mood swings, aggression, agitation, really easily annoyed, &amp; hostile. my doctor decided to put me on adderall xr 10mg tablets &amp; let me tell you it has saved my life!!!!!! it lasts all day for me, i am more focused, my heart rate doesn&#039;t jump to extremes like it did on focalin. it actually makes me more relaxed &amp; enjoyable to be around. 10/10"
