When you stop taking Vyvanse, you may experience withdrawal symptoms such as fatigue, depression, increased appetite, and sleep disturbances. These effects can vary in intensity and duration depending on the individual and the duration of Vyvanse use. Vyvanse detox and treatment programs, including both inpatient and outpatient options, can provide necessary support. Medical supervision and professional advice are crucial during this process to manage severe withdrawal symptoms and to ensure safe and effective addiction treatment options.
