Deliquesce,

Wow, this drug sounds powerful, almost like a narcotic street drug. EEK! It's actually like a sister to meth! I'm not sure I would take it, no wonder your doc wants you to research it first. Anyhoo, here's a place to start looking and I've copied a bit of the info for you below, so you can make your own decision.

Clinical

• Approved for the treatment of ADHD and Narcolepsy.[22]
• Treatment for depression and weight-loss may be prescribed in rare treatment-resistant cases.[23] [24]
• In all clinical treatment scenarios, the dose of dextroamphetamine should be increased gradually from/by 2.5-5 mg/day every three days-week in order to help prevent abuse by minimizing the initial euphoria and effectively estimate the minimal dose required for each individual in treatment of the relevant condition.[25]
