"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) &quot;a manufacturer backorder&quot;.

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&#039;t get a headache to boot. so overall i have to say the dextroamphetamine is significantly better than adderall on several levels."
