In Reply to: Ritalin Switch to Adderall Dosage Question posted by Charles on September 04, 2000 at 16:57:03:

adderall is not time released but because it has several different ingrediants that are metabolized at different times it generally lasts 4-6 hours. he could always take the second dose earlier. otherwise the dosage seems pretty reasonable.
