But typing all those long words is so darn hard!
Adderall is a mix of dextroamphetamine and levoamphetamine and affects the neurotransmitters dopamine, seratonin, and norepinephrine, by blocking the reuptake of those neurotransmitters. Thus, it acts on the receptors for those neurotransmitters.
If there are more technical names for receptors in the brain, it's beyond me, but I hope this helps.
I don't know that there's a way to rehabilitate neurotransmitter receptor sites beyond stopping the Adderall, but again, my knowledge is limited.
