What symptoms are commonly experienced when stopping stimulant medication?

When people stop taking stimulant medication, it’s common to experience a mix of physical, cognitive, and emotional changes as the body adjusts. Many report temporary physical symptoms such as fatigue, increased sleepiness, headaches, appetite changes, or a general sense of moving more slowly. Cognitive effects often include reduced focus, slower processing, difficulty initiating tasks, and mental “fog,” which may feel more noticeable because the contrast from being on medication is so sharp. Emotionally, people sometimes experience irritability, low mood, reduced motivation, or feeling unusually flat. Most of the physical and emotional symptoms tend to be short‑lived as the nervous system recalibrates, while cognitive symptoms may persist if they reflect underlying ADHD rather than withdrawal.
