"i&#039;m 21 years old and i&#039;ve been on 40mg vyvanse for about 5 months give or take.  i&#039;ve been on other medications for adhd in the past, but they left me feeling edge-y or more anxious.

this medication works much better in terms of even release and feeling normal, and not jittery or like i have a come down when medication wears off.

however, i still struggle trying to find the ideal medication/dosage because my days are long, sometimes from 4am until 10pm  at night, and no medication has lasted that long for me.  

i used to take adderall twice daily, so that it would last me the entire day, but that left me feeling terrible.  i fear if i up the dosage of vyvanse to twice daily, i may start getting other side effects as well.  "
