Starting treatment
What to expect your first day in treatment
The first day of treatment is often the scariest — not because of what happens, but because of the unknown. Knowing what to expect can reduce anxiety significantly.
Residential treatment: Day one
You will go through a structured intake: medical screening (vitals, history, medications), clinical assessment (substance use history, mental health screening, risk assessment), and facility orientation (rules, schedule, expectations). Belongings are checked — most facilities restrict phones (some allow limited use), sharp objects, outside medications, and alcohol-based products. Bring comfortable clothes, basic toiletries, ID, insurance cards, and prescribed medications in original containers.
Detox: What happens first
The medical team assesses severity of physical dependence and creates a detox protocol, which may include medications for safe withdrawal management. The first 24-48 hours of alcohol or benzodiazepine detox involve the most acute symptoms; medical staff monitors you closely throughout.
Outpatient or IOP
The first session is usually an intake appointment — a one-on-one assessment with a clinician who explains the program structure and begins your treatment plan. IOP typically runs 3-5 days per week, 3 hours per session.
What everyone should know
It is normal to feel anxious, scared, or resistant — most people do. Staff will not judge you. You do not need to have everything figured out. The hardest part is the decision to go. Once you are through the door, you are surrounded by people whose job is helping you through this.
