How do I know when adderall is wearing off?

You may know Adderall is wearing off when you start to feel a decrease in focus, increased fatigue, or a return of symptoms related to ADHD, such as distractibility or impulsivity. You might also experience mood changes, irritability, or difficulty concentrating. Physical signs can include restlessness or a decrease in energy. If you're noticing these changes, it may indicate that the medication's effects are diminishing.
