I posted this in reply to another member on another thread, but why not post it again within its own specific subject? I hope it might help inform somebody:
I am in the UK (south-east England). I have been through three detoxes. Two private and one on the NHS.
The private detoxes lasted around a week. They used Librium, which is the detox sedative of choice over here. They also boosted me with Thiamine and Vitamin B (strong) complex.
It was not in the Priory, which you will have heard of, but a similar local private institution which was lovely. The rooms were like a very nice hotel, the food in the restaurant was top-class (REALLY delicious!!) and the counsellors were absolutely superb. I had wifi access, I was allowed my mobile phone, and to make calls out on the staff telephones. This is very different from the tough regime I have heard of at the Priory.
Unfortunately the counsellors were all ex-addicts themselves, and so every session they tried to help with my issues (basically low self-esteem, and failure to grieve properly for a lost relative) were also aimed at persuading me that abstinence was my only route forward throughout the rest of my life. TSM and the Baclofen treatment that I am recently interested in have convinced me otherwise. Attending AA, CA and NA were part of the programme.
I have to say that Librium works excellently as a detox medicine. Even with it though, staff would check on me throughout the night to make sure I didn't have any seizures. In my second detox I believe that I had some sort of brain trauma (a mini-stroke?) because I was asked to read something out at an AA meeting, and although reading has always been my greatest strength, I struggled so, even though I was almost off the Librium. Once I am fully sober and CURED I'll be pushing my GP to send me to a neurologist to check up on this. Something has happened there, although I am not too bad - in fact almost back to normal (although I am a committed alcoholic once again

).
Both times I stayed for the minimum time for the detox - 7 days, purely for financial reasons (I was self-funding and it costs about £500 a day). The counsellors wanted me to stay for at least two to three weeks to fully deal with my issues, and I wish I could have, because they were SO excellent at dealing with emotional stuff, absolutely superb. If anybody would like details of where this place is please PM me. I also have an acquaintance who went to a similar place (don't know quite if it was 5* like mine, but it was meant to be very nice) in Scotland, where it cost 'only' £1500 per week.
Most of the patients at this place were covered by private health insurance (Bupa covers it I know) and stayed for up to 28 days.
My third detox/rehab I had no more money, so had to go NHS. I'm no snob, I would have done that anyway, but the private place admitted you on the very day you wanted (and the levels I was drinking then, much as I am now, made me absolutely desperate.
Again, they used Librium. I was lucky, as the facility was new and very comfy - apparently the previous place was an NHS nightmare, from the mould on the walls to the rats scuttling round at night. The staff were excellent, but the other patients were mainly heroin/crack cocaine addicts. It seems that alcoholism takes a very back seat to drug addiction (probably both politically and because of the greater associated crime that comes with drug abuse) in Kent.
I stayed for nine days, which I needed by then, as the waiting list kept me out from there for almost four months, by which time I was in a terrible state. I had not been able to eat properly for months by the time I got in there, and was almost a walking skeleton. Why? Because of my drinking the excess stomach acid meant I couldn't hold food down. Alas, my GP didn't have the foresight to prescribe, or even recommend, a simple antacid which would have made the world of difference.
We heard that one girl died just days before she was due to be admitted, because the waiting list was so long

It was also a different kettle of fish from my private detox. They confiscated your mobile phone at the door (so people couldn't phone their dealers for drugs) and it was more regimental - with times to get up and go to bed. The counselling was generally lousy, although the day staff were absolutely dedicated, to a fault.
