"i&#039;ve been on vyvanse for about 2 days now and i can&#039;t believe the difference from the other two medications i&#039;ve tried. (adderall and focalin) i was diagnosed about a year and a half ago, i was not diagnosed when i was younger, which would&#039;ve have really explained a lot.  first i tried adderall, it didn&#039;t do much but make me a bit irritable, and still not focusing was on 50mg a day 30mg in the morning and a 20mg in the afternoon, and i didn&#039;t notice a thing. next was the generic of focalin, which dild absolutely nothing! with vyvanse i feel like i can concentrate on one thing at a time, and not have the urge to start 10 other things.  my doctor put me on 70 mg in the morning, it&#039;s a bit of a slow start, but once it doesn&#039;t its a very productive"
