Hello and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Adderall contains a combination of amphetamine and dextroamphetamine. Amphetamine and dextroamphetamine are central nervous system stimulants that affect chemicals in the brain and nerves that contribute to hyperactivity and impulse control. It is used to treat narcolepsy and attention deficit hyperactivity disorder (ADHD). People who take large doses of Adderall for prolonged periods of time run the risk of becoming physically dependent on the drug. When this happens, a tolerance builds up. However, withdrawal from stimulants like Adderall often results in relatively mild physical symptoms that are unpleasant but not generally life-threatening. Prominent psychological dangers during withdrawal include including depression, anxiety and drug cravings. Symptoms of withdrawal from Adderall can begin anytime from hours or days after the last use. These symptoms may differ depending on the individual and their personal history of using Adderall. In general, it can be: Extreme fatigue, Sleep disturbances, Intense and vivid drug-related dreams, Hunger, Memory impairment, Drug cravings, loss of interest in pleasurable activities, Anxiety and Depression. Seek medical attention immediately when these symptoms continue to exist or becomes bothersome. Hope I have answered your query. Let me know if I can assist you further.
