"i&#039;m a 31yr old female, 5&#039;4, 115lbs. i was 1st prescribed adderall in 2012, so i&#039;ve taken it about 3 1/2 yrs. within that time there&#039;s ben a few situations that forced me 2 go with out meds for a week or more, which reminded me how much it helps! without it i could sleep 18hrs for days &amp; still be wanting 2 sleep an hr or so after getting up! i can sleep while taking it, but don&#039;t have the strong compulsion to. the first day taking it i&#039;ve learned 2 only take half bc if not it feels like i&#039;m on cocaine, even after just a week of not having it. but the 2nd day &amp; thereafter is fine.i  never experiencd any &quot;comedown&quot; like some ppl. the only negative is without it i get agitated easily &amp; get on my own nerves when it comes 2 lack of concentration, forgetfulness,n sleeping 2 much."
