I went to state-funded rehab in Massachusetts this past year. Over here, that consists of several stages: detox, CSS(clinical stabilization services), TSS(transitional support services), and halfway/three-quarter/sober house.
First, I went to a detox center where just about everyone was bitching about their med dosages(typically, they were never enough, although mine was fine). The food was sometimes good, but I have several texture issues that make eating in public a nightmare, so I knew the food would be an issue no matter where I go. I was there for about five days.
After detox, I was sent to the CSS, which is a 2-4 week program, depending on your insurance. It's basically the actual rehab, with all the groups back to back. Our movement was very restricted there. From 7 am until 9 pm, you could not be in your room, except for a 90-minute "quiet time" break you got after lunch. And even when it was finally 9:00, you still had to wait until you had taken your meds before you could go to bed, so you could be waiting until almost 10 to finally get to lie down. This could be very unpleasant if you were still detoxing(and many people were) and just wanted to lie down. During the day, you were in back-to-back groups. Men had to sit on one side of the room, while the women had to sit on the other. We also were not allowed to leave the dining area until everyone was finished eating.
I stayed there for 2 weeks and then moved on to the TSS. This is basically a holding facility where you stay while waiting for a bed to open up at a halfway house. The detox and CSS were co-ed, but the TSS was a women's facility. The men's TSS is one town over. There are less groups and more free time, but that sadly allows for a lot of drama to happen. I kept myself sane by reading lots of books I'd brought with me from home, and listening to a lot of music. CD players, radios and mp3 players are allowed there, and I made sure I was plugged into my music. There were public AA meetings in the basement of the facility 4x a week, although I didn't go to many of them(they were optional), as I don't believe in the 12-steps. Every Sunday, staff would bring us to Walmart, and most of the women would load up on snacks. As I mentioned above, I have food issues, so I would buy ingredients for sandwiches, instant rice, canned pasta, protein shakes, etc. so that I could opt out of the disgusting hospital food they served. They had a Smart TV with Netflix and YouTube, so we often binge-watched shows like Shameless and Orange Is The New Black. There was also an outside meeting that all the women would go to except for me, so I'd get to stay behind and have the TV all to myself.

I stayed there for 51 days waiting for a place to open up. Some women have been there as many as three months.
None of these facilities allow smoking, as tobacco is practically against the law in Massachusetts. Every mall, college campus and hospital I see is "tobacco free", and these places are no exception. Thankfully, I have no desire to smoke while sober(although I'm a chain-smoker when I'm shooting up). Sadly, a lot of people end up breaking the rules by sneaking cigarettes and getting thrown out. The TSS would at least let people smoke during the Walmart trips, and during the outside meetings(which is why everyone would go to those meetings except me).
While detox is obviously crucial towards getting clean, and halfway houses provide a safe environment for you to get your life and your head together, I feel like CSS and TSS are just going through the motions. I especially dislike the lack of knowledge the staff have of other programs other than the 12-steps, such as Refuge Recovery and Smart Recovery. Many staff didn't even know what those were until I told them. Having been force-fed AA and NA during my time in treatment, I now have the goal of becoming a SMART Recovery facilitator, and trying to bring meetings into these facilities. I'm still in contact with staff from the TSS, and they seem eager to have me come in and do "SMART commitments" once I'm certified. The 12-steps have too much of a monopoly over most rehab centers, and I want to see clients being presented with other options.
I'm currently living in a sober house, and all in all, I'm pretty happy. I'm working, saving money, and 5 months clean. I just feel like most of my treatment up until this point consisted of me going through the motions and jumping through hoops. It's not the first time I've been in treatment, and I feel as though the more times I'm in treatment, the less I get from the groups, as I've already heard it all before.
Still, it was worth it to get to where I am now, so I guess that's something. I'd just like to see things improve, which is why I want to help in the way I mentioned above.
