I was on Ritalin 120mg day, developed tolerance. Now Adderall 120mg, but unhelpful & side effects. Would Focalin (dexmethylphenidate) be better? & what dose comparable?

See below. Focalin (dexmethylphenidate) XR might feel better than Ritalin for some with ADHD. But tolerance to a medication typically requires being off. Dosing is best left to the psychiatrist who can evaluate you as it will also need to include weighing tolerance, symptoms and side effects.
