There is a retired doctor in Uk called Dr chandy who has campaigned for a better understanding of B12 deficiency. I spoke to him a couple of weeks ago, described my history, my poor memory and balance at that I had been reffered to MS specialist. Dr chandy is quite a religious man and seems to see it as his little god given mission to see that people get B12. He doesnt charge for consultation, relies on volunteers and tries to fund as much of the B12 as he can himself, so there are no purse strings involved like with so many alternative health ideas. He told me he does not beleive there is any MS or dementia or chronic fatigue and that it is all about getting B12, thyroid hormones and vit d right. I had my first injection of B12 last might and he advised every day for 2 weeks. I have good days sometimes but this is the best I have had for many years and I actually remmbered the name of an acquaintance. It feels as if I am waking up from a bad dream. Has anyone else tried B12?
