I mean increase his dosage..Since he is often missing his night does, that alone could be the reason its not working for him.. Might want to consider switching to concerta or a drug that is not highly affected by a missed does..Strattera although a time release only releases for a certain amount of time (till the next dose) "per my understanding" I can tell when my son has not taken his right.. grrrrrrrrrrr

good luck
