"i have found that dextroamphetamine er cap (aka dexedrine spansules) are best for treating my adhd.  i have tried ritalin and adderall and both came with bad side effects.  ritalin made me a zombie and adderall had sexual and hyper-tension side effects.  the switch to dextroamphetamine has increased my focus, alleviated my adhd symptoms, and also increased my sex drive.  i had to take 10mg x 4 adderall but find that 10mg x 2 dexedrine er works for me.  so i was able to decrease my intake of amphetamine while switching to dexedrine.  after 1/2 year, i have found no negative side effects whatsoever."
