i don't have a lot of experience with adderall, but the past few 4-5 months i've developed a habit of taking 10-20mg on the weekend before i go out drinking. at first 10mgs would get me going so hard that i had trouble being quiet and sitting still. seriously one would have me fucking raging and i think it was pretty obvious to anyone looking for it. i would wake up and still feel it the next day. now, after about 5 months of weekend use, 10 mgs is hardly noticeable. the last 2 or 3 times i took it the effects besides an elevated heart beat were almost unnoticeable, almost like a mild caffeine buzz. i refuse to take more than 30 mgs because of the way it makes my heart rate tho. the first few months was 1-2 times a month, 10mgs maybe 20+ some nights whick slowly progressed into 10-30mgs both friday and saturday. addictive? i;d say probably as addictive as vicodin. if you don't make it a habit then you;ll be good, but i can definitely see how people easily become addicted to adderall. for the next day or so after taking adderall your left feeling unmotivated, tired, and irritable. even more so after a binge. taking them daily will slowly drive you into a darkness until you only feel normal or level when your on adderall, which is what doctors call chemical dependence.
