I read something about
this really recently. It won't be of any help to non-UK readers unfortunately but apparently there's a doctor in Oxford who's offering them to patients. The results were fairly impressive, given that these are patients who have responded to nothing else previously, e.g antidepressants, therapy.
If I can find the article again I'll post a link.
