"i have been diagnosed with adhd and since then my life have been a total wreck. i didn&#039;t get any work done in school or focused on anything also forgetting a lot of things frequently.  i went to my psychiatrist and she prescribed me vyvanse 30mg. the first day i took it i felt awesome i focused more and i was very talkative which is normal for me, anyways no change there. but since i&#039;m 5&#039;9 and 230lbs i need the weight loss so that&#039;s good for me. right now i double dosed because i want this to last longer not until 12p.m."
