There are some things that any addict or alcoholic might want to know about drug rehabs or addiction treatment centers before they commit to checking in to one. First of all you will probably go through a medically supervised area in which you will detox, and this may last for the first couple of days of your stay there. Normally, depending on what drugs or alcohol you are detoxing from, you will be kept in detox under the supervision of medical staff for about three to five days. Of course these are just averages and some people will be in detox a bit longer and other people might not need detox at all.
Next you will likely go into residential treatment for about a week or two. This is where you attend groups, therapy, lectures, watch videos, and talk with counselors. You will also probably attend 12 step meetings at most rehabs, though some places might have other forms of treatment other than the 12 step program. You will probably meet with a lot of peers who are in the same basic situation that you are in. They will all be trying to get clean and sober just like you are in fact.
Usually you will be assigned a therapist to work with you and that therapist will come up with a plan for when you leave treatment. They might recommend outpatient treatment, meetings, or even long term care for you when you leave. Most people who manage to stay clean and sober have followed these aftercare recommendations and done the necessary footwork that was suggested to them.more from here
