Another of the facilities I recommend the most is Castle Craig Hospital, Scotland. Set in lovely Peebleshire countryside their website explains:

Expert Treatment for Drug and Alcohol Addiction

Over 10,000 patients have passed through our doors since 1988, and the majority have gone on to achieve, long-term abstinent recovery from their addictions.

Our expert medical team of doctors, nurses and therapists are led by our Consultant Psychiatrists and Medical Director. We help our patients recover through an intensive, personalised programme that combines medical treatment, a 12 Step programme, CBT and other psychotherapies, complementary therapies and continuing care.

For more information give me a call and I can assess your needs.
