"was on concerta 18mg for 3 years worked great. stopped taking it, felt like i didn&#039;t need it anymore and i didn&#039;t want to pay for it then. wasn&#039;t doing so well professionally or at home not getting chores done feeling real lazy etc. so i went back on the concerta couldn&#039;t feel it this time bumped up to 36mg still most days didn&#039;t feel a difference tried vyvanse definitely can feel motivation only doesn&#039;t seem to last as long as concerta used to for me but i feel happy on vyvanse, just wished it lasted longer also as a lot of people say less anxiety. i can say i don&#039;t have an anxiety problem on concerta or on vyvanse but vyvanse feels like it has anti-anxiety medicine built into. i feel real comfortable where ever i go."
