Hi Nancy,   Thank you for taking the time to reply to me. Unfortunately the Edinburgh clinic listed on the Migraine Trust web site no longer exists!! - I had already investigated that one and had been told that the doctor who ran it had moved away. So I have hit a bit of a brick wall there. I am going to try asking my GP to refer me to the Homeopathic hospital in Glasgow, which is about 40 miles from Edinburgh, as I understand they have an excellent headache clinic and the National Health service will refer patients there, although the waiting time for an appointment is about 3 months. Thank you again for trying to help. Cheers Margaret
