not all add drugs are amphetamines (wellbutrin, strattera) and some ssri's function also as an add relieve.
Me personally, as an recovering addict (i am now 27 days sober

) had some relief from concerta, but it did not take long before i started to abuse them, apart from that, it fucked up my ability to think out of the box and notice the things happening around me sharper then the avarage person, lets call them the positive ADD symptoms.
I am now off add meds, and i am pretty fine with that.
I take effexor for my generalised anxiety disorder and depression, and i feel more relaxed anyway, im no zombie or anything.
The annoying thoughts that keep on going when i try to sleep are now a subject to a low dose of mirtazapine, so i can just sleep.
By the way, what you experience doesnt mean you have add, there are many other disorders that have those symptoms.
Go to a psychiater to find out.
good luck
(and dont do drugs)
