"i was diagnosed with adhd when i was 19, and i&#039;m now 23. i have a &quot;severe&quot; case as my psychologist &amp; therapist would say in the 1 visit i met with them. i started out on adderall and adderall xr, but had to stop taking it due to the side effects like mood swings and parkinson&#039;s like shaking in my hands. so my dr changed my meds to vyvanse. i&#039;ve been taking it for 1 yr and i no longer have mood swings or shake which is awesome because i don&#039;t think someone would like a shaking dental hygienist. i like vyvanse because it still helps me concentrate, stay organized, and remember things that are told to me, but it wears off quickly. that is my only dislike about vyvanse."
