Adderall is the only one that has ever worked for me. Of course I had to try and fail on dozens of other meds before finally finding one that worked.
Believe me it is definately worth all the waiting when you finally find the right medication. If the concerta isn't right don't give up most likely there is a med out there that will help you.
Oh and I saw you switched from Adderall to Concerta are you on anymeds for the depression or just for adhd. If you're not being treated for the depression along with the ADD that could explain your miserable feeling.
