"i am only giving this a 7 because it definitely made a change in my ability to concentrate for long periods but it was not a pleasant experience. as soon as i took the medicine it would make me feel exhausted and tired. i would have to fight the tiredness to get any benefit out of it. by the end of the day i was drained. it also made me extra agitated. i couldn&#039;t focus on more than one thing at a time so when someone would distract me i would get very irritated. i also tensed up my muscles and had bad neck/bad pain. i switched to ritalin but that was crap too. they put me on vyvanse and it feels similar but less intense than adderall so we shall see."
