"evekeo works great. it&#039;s more mild in regards to excitability in comparison to adderall.  evekeo is amphetamine sulfate and carries 50% dextroamphetamine and 50% levoamphetamine.  adderall is 75% dextroamphetamine and 25% levoamphetamine, so evekeo is much smoother and wears off slowly vs adderall&#039;s fluctuating tapering.  it is much different than adderall.  evekeo doesn&#039;t make you feel wired like adderall does.  it&#039;s a cleaner medicine.  evekeo is a freebase amphetamine while adderall has 4 different salts.  i would recommend the makers of evekeo to make higher milligram tablets.  it&#039;s similar to a 10mg adderall ir.  it&#039;s just the ratio of ingredients that&#039;s the difference. duration is said by pharmacists to be 12 hr&#039;s, buts more like 6."
