First off, I recommend you ask a licensed professional that type of question. My experience being switched from Adderall XR to Vyvanse a few years ago when it first came to market in the U.S. has been positive. Vyvanse seems less addictive (missing a week or two between prescriptions is not a big deal) or prone to side effects like insomnia.

This was my experience as well. After 6 months on adderall I had already shown signs of addiction (dosage was needing an increase in order to maintain its effectiveness). I have been on the same dosage of Vyvanse for 4 years now, without any problems.
