Bring a clear symptom timeline
Before the visit, note when sleep, mood or behaviour changed and whether those changes occurred before, during or after substance use. Discuss this timeline privately with the clinician; an online symptom list cannot establish a diagnosis.
Prepare the medicine history
Bring the names of prescribed and over-the-counter medicines, previous treatment records where available, and questions about benefits or unwanted effects. Do not alter an existing prescription simply to prepare for the appointment.
Agree the follow-up questions
Ask what should be reviewed next, how follow-up is arranged and what to do if symptoms worsen before that visit. Our dual-diagnosis guide explains why psychiatric and substance-use concerns sometimes need a shared assessment.
