Amphetamine / dextroamphetamine
"Adderall XR does exactly what it's supposed to for me.  I suffer from very little noticeable side effects.  The most noticeable ones are insomnia when first taking this medication, lack of hunger in the beginning, and slight dry mouth. Overall the side effects are not bad at all.  The only negative for me is it feels like the medications stop working after 6 hours for me."
