"Detox 5" program in UK- rapid heroin detox??

[latter]

My daughter has a 3 year heroin habit - athough has spent the last 16 months on methadone replacement.



She now really wants to go clean, however, has tried going cold previousely and has never made it past day 3.



She now wants to try an ultra rapid detox and a friend has recommended
a clinic here in the uk called detox 5. This a rather sudden 5 day
program consisting of 3 days anisthisa and then - so it seems to me -
being shoved out of the door on naltrexone



I have serious doubts about both the method and the clinic - their
rather flashy media claims 98% success rate (although they don't seem
to quite qualify what a "success rate" is).



Before she takes the step to enter this program can anyone here tell me if they have any experince of this clinic or similar?
