I didn't say it's a question of building up the desired effect. From experience with our son, however, I do think you need to wait at least a couple of weeks before you can make a conclusion that a medication is/is not working. The various stimulants can have varied effects and they don't manifest immediately in many cases.
In any event, the OP was expressing concern that a medication was not working 10 hours after taking it. Even at its best, Vyvanse is on the wane after 10 hours and it may not be realistic to expect a teen to write a detailed paper at that point.
