The B12 issue was picked up a year ago at another practice. I had to go for weekly injections and then they were supposed to have been tapered off to monthly for the rest of my life. Unfortunately got thrown out of that practice,cos the doctor's said I was costing them too much money. Anyway, bless her, the doc at the private hospital has said that my condition is so serious, shes sent a letter to my GP. Don't hold out much hope there, but she's so concerned she said if nothing happens quickly, I must go back to her for free. She knows more than all our quacks put together! She has treated literally thousands of people with heavy metal toxicity and cares agreat deal. Thanks for advice Tracy x
