I have lost all motivation interest & pleasure in life after 5 yrs of adderall (dextroamphetamine and racemic amphetamine) abuse? after many failed attempts, what are the best supplements/vitamins to to aid me in restoring my brain & body?

Stimulant abuse: may cause problems with your dopamine that may take months to correct. After 5 years of abuse it may take some time to restore the dopamine function to near normal.

Still AddictionFocus: Addiction=using ANY chemicals/supplements/vitamins/diversions, etc. to avoid feeling/solving Soul/Mental life issues vs. numb/distract/avoid dealing with actual internalized issues: e.g. short term stimulants, pain killers, psychotropic agents, over-eating/drinking, abusing self/others, sex without responsibility to partners, etc. Seek assistance both worthy of your trust & holds you responsible.

Addiction, depressio: YOu need to see a professional who is competent in understanding addiction but also able to judge the presence of depression, which may need treatment.
