Stimulants have the adverse effect of harming the mitochondria/metabolism.

Most conditions improve when the metabolism is normalized. B-vitamins are pro-metabolic.

Sometimes doctors do good work. My girlfriend's doctors eventually figured out that she is a poor methylator, and can't convert folic acid into folate (Vitamin B-9). She therefore absolutely requires a dietary source of Folate, instead of the folic acid that is used to fortify many foods. She said this vitamin was profoundly helpful for her complaint of "depression".

Sometimes doctors make work for themselves. Using Stimulants to treat metabolic problems is an exercise in futility.
