ive read the package inserts and they all have said things like that the patient should be reevaluated in x amount of time to see if the med is still beneficial.

sometimes the affliction is healed because the brain has learned to fucntion through the use of the meds. maybe like a tutor... who catches the child up to the reading level and he doesnt even need a tutor anymore. in fact then the tutor would hinder other parts of development. maybe it is the same with medication.

and they don't call it "practicing" medicine for no reason.
