Thanks for your replies, just spent a while doing a better response than this, and lost it in the digital ether, so apologies. Madelyn and Chicory, yes, to all you say, and Fiona, I read your posts with great interest, and look forward to you take on this. I agree, it is big. It is there, and it presents people with obstacles they could do without - seems like medicines insecurities about its own validity are bounced right back to the patient!
