What is the max dose of Adderall daily?

The maximum dosage of adderall that a shrink will prescribe is 60mg to be taken over the course of the day in three 20mg tablets. However, that is a patently absurd amount of amphetamine to be ingesting on a daily basis - not only is it incredibly bad for your heart and mental health (google 'amphetamine psychosis') but it will almost certainly result in dependency.
