In the UK many GP's and hospital doctors follow the NICE guidelines and the type of treatment Dr Myhill offers is not included. There has been huge arguments and a legal case brought by patients against the NICE guidelines but little sucess. It's a postcode lottery with some GP's prescribing things like B12 and other refusing to do so. But one doesn't need a GP to follow the Myhill suggestions as they are things that can be bought OTC or privately or from abroad. It boils down to money sadly.
