I've been to rehab twice, and would t be clean today without it. Rehab saved my life. My rehab was structured. Went to bed early, woke up at the same time every day, three meals a day, same time every day. We had group therapy daily, gender based therapy (sexes are segregated) a couple of times s week, meetings a few times a week, and some other activities. In theory, we were supposed to receive counseling but I saw the psychiatrist once for five minutes and the counselor twice for about ten minutes each time because he facility as so overbooked. The food as gross, the facility dirty, and many of the other patients belonged in an asylum, not rehab...but, being there for thirty days kept me away from the stress of my life and kept me away from substances. I also learned a lot about addiction and recovery, and learned valid tools to live as a sober person.
I now live sober, my marriage is no longer stressed by my using, I work full time, and I have hobbies and friends, and live a nice quiet normal safe life. As unpleasant as rehab was, it was necessary to get healthy. Of course, this is only my experience. I can't tell you what rehab will be like for you, or if it will work for you. Your attitude going into rehab will determine what you get from it, and how you apply that knowledge to better your life. Essentially, you get what you put in, so I recommend you work hard while you are there, regardless of how ridiculous the task may be, and try to learn everything you can about addiction, recovery, and yourself. Feel free to hit me up with questions. Good luck! You have a great opportunity in front of you - take advantage!
