I'm on day 5 taking 36 mg's of Concerta. I've noticed the "can't get to sleep" side effect and understand it needs to be taking immediately after I wake up. When will Concerta be completely in my system and my A.D.D. will be controlled?
When does Concerta start working? Days? Weeks? Months?

Concerta should work the very first time you take it. If you are not noticing any helpful effects, please speak with your doctor, as an increased dosage of Concerta(or change in medications) could be beneficial.
Concerta is a extended release medication, so the peak(highest amount in your blood) will be approximately 6 hours after you take it.
Insomnia(inability to go to sleep) is a common side effect of Concerta and other stimulant medications(Adderall, Dexedrine, ect.) If this is bothersome, please speak with your doctor.
