Hi. i was just wondering if you can get addicted to Dextroamphetamine right away or if it will take time. i feel like im already addicted to it and having withdrawals when i don't take it every 5 hrs. The first time i used it was yesterday (11/3/14) at night so i could stay up and finish school work. i took about six 5MG tablets that night. could i be addicted to it this early. and also, is it normal to feel high when you take it. Thank you.
