"I had been taking Adderall (generic) for approximately five years but recently switched to dextroamphetamine because it was getting so hard to get Adderall due to (as the pharmacy said) "a manufacturer backorder".

But talk about serendipity; the dextroamphetamine makes me clench my jaw a LOT less than the amphetamine salts and as I begin to lose focus at the end of the day I don't get a headache to boot. So overall I have to say the dextroamphetamine is significantly better than Adderall on several levels."
