You didn’t really titrate the dosages in the way it’s recommended. You should start at the very lowest dose and only increase if and when needed (Concerta’s lowest dose is 18 mg, and the highest is 54 mg, although some clinicians will combine two pills to prescribe 72 mg). It could be that you require a really high dose, or it could be that you do better on amphetamines than methylphenidates. It’s a lot of trial and error to get the right medication and dose.
