Switching from Concerta to Adderall?

[deadmoap]

I was prescribed 18 mg of Concerta last week. The therapist said that
concerta has a lower chance of an anxiety attack and she's giving me
the lowest dose, because she wants to be careful. Well I've only had
one anxiety attack in my life, and that was two years ago... I don't
have anxiety and it's not something I worry about.



But what should I tell my therapist to get switched to adderall? She
said that if there's something wrong with concerta, then I can try
adderall, and after that, then I've already tried the two most
effective medicines for ADD and there are others that don't work as
good and have more side effects. So getting switched to adderall isn't
out of the question, and I obviously need to tell her that I haven't
been having any problems with anxiety, but if concerta is working, then
why would I switch? Obviously because I want a better high, but I
probably shouldn't tell her that. I'm already under suspicious because
I have a history of drug abuse (I'm on probation for possession of
marijuana).



Are there any specific problems with concerta that don't exist with adderall?
