"i was diagnosed with adhd at eight . i was put on ritalin then. awful stuff. that turned me away from  taking anything for years. i started taking adderall xl at the age of twenty-seven. i didn&#039;t notice a change until my doc raised my dosage from 20 to 25mg.  my work was better. heck my life turned around.  i finished projects i started. i payed attention. i remembered little things that use to evade me. like names, where i put things, and what i was just doing. i also noticed i wasn&#039;t as depressed. i could sleep better. just do not take xl late or sleeping may be difficult. one thing and i can&#039;t stress enough. if you have a loved one who is on or going to be on adderall. it is addictive. watch for the signs of abuse. monitor teens."
