shsu.2009 Posted May 31, 2011 Share Posted May 31, 2011 Hi, I was percribed vyvanse 30mg a couple of weeks ago and it worked well at first, but recently i had felt the medication fizzle out after a few hours. Should i ask my doc to up the dosage or should i see about switching to adderall? Thanks! Link to comment Share on other sites More sharing options...
