I think Adderall (dextroamphetamine and racemic amphetamine) is effecting my labido? Is this a side effect of all ADD drugs? Is there something I can take to counter that side effect?

Probably not. Adderall (dextroamphetamine and racemic amphetamine) is sometimes prescribed to counteract the libido diminishing effects of other medicines, so it is a surprise that it may have that side effect for you. I would suggest that it is not the cause. But if it is, you would do best to switch, since Add drugs d'n't have this side effect; and beware of claims that drugs are not drugs and that they have broad, magical powers.
