If you are considering detox, the unknown is often scarier than the reality. Here is what actually happens.

Arriving

You will be nervous. That is normal. Staff will evaluate your vitals, medical history, and substance use. Your belongings will be checked. You will receive a room assignment and orientation. The whole intake takes 1-3 hours.

The first 24-48 hours

This is the hardest part physically. Withdrawal symptoms are at their worst. Medications manage the worst of it, but you will not feel good. Staff monitor you regularly. You rest, hydrate, eat when possible, and let your body begin healing.

Days 3-7

Symptoms begin improving. You start eating normally. Energy slowly returns. You may attend light programming (psychoeducation, group check-ins). Sleep begins improving. You start feeling human again.

What it feels like

Honest answer: uncomfortable but manageable with medical support. Far better than unmedicated withdrawal. Most people say the anticipation was worse than the experience. The relief of being in a safe place and getting help is profound.
