"i&#039;ve been on this medicine for about a month and lost around eleven pounds. i initially got on it to stay more focused in school although i don&#039;t have a serious case of add but i don&#039;t mind the weight loss. i could spare a few pounds. you get a rush for about 45 minutes after it kicks in and that feels better than it should. i feel i can concentrate when i use it, but i&#039;m not myself when i take it. my personality is dulled a bit and even if i have homework to do, i&#039;ll find something to distract myself. whether it&#039;s choosing a simpler assignment or just writing because i still feel like i&#039;m being productive."
