How relevant to the UK is Dr. Kharrazians book?

This is not going to be very helpful as an answer. Certainly the Yahoo groups are awash with him. But I have no personal knowledge - having not read his book and not even read much about what he recommends.

I am, however, deeply sceptical of anyone who has a mysterious "protocol", whose apostles seem to sign up for training, and then go off selling their newly-gained knowledge at considerable cost. It has the looks (from afar) of pyramid selling scams.

At the same time, maybe he has got something of potential real benefit?

And I have not yet heard of any UK-based person who has been trained and is offering the protocol.

If you do decide to buy, do let us know what you think?

All the best
