Does l-tyrosine help in any way if you go off adderall (dextroamphetamine and racemic amphetamine)?

For Some People: Tyrosine is helpful for some people as far as improving focus and attention. However, it is likley to be a more gradual, subtle benefit, so you should not expect to see the kind of rapid benefit that we often see with adderall (dextroamphetamine and racemic amphetamine). Also, for some people tyrosine will simply not be helpful enough.
