i've been on adderall for about 2 years now. its been my best friend and worst enemy. whenever i try to go off it completely the first few days i am extremely hungry, i sleep non-stop, and i have no motivation to do anything--its horrible! but after the first week your body will balance out to how it used to be. my advice to you is don't go off it completely, take less and less each day and gradually go off it, that way the side effects will not be as bad. hope this helps
