"i was prescribed adderall xr for lack of focus and attention. after being on the medicine (10 mg) for 4 days i felt very confused and had trouble talking. i was stumbling over my words and second guessing myself. my appetite was altered (as expected) but i made sure i ate frequently. i also noticed i was very impulsive and short tempered, more than usually. i just wasn&#039;t my normal self on this medicine. i&#039;m glad it has worked for many people, but it did not agree with me."
