I have severe neuropathy and have had no NHS help for 8 years. I had nerve damage due to surgery, infection and lots of antibiotics which definately led to B12 defieciency as my 2009 MAP showed elevated MMA levels. I do very well when on B12 HYDROXY and ADENOSYL at doses over 25mg each daily. This obviously costs alot so i have only done twice for a few months. I can't possibly afford this now or anytime soon. Low b12 doses do nothing even upto 15mg. Without b12 my nerves are super sensitive, tight, i have sensitive eys etc when i use mega doses it stops and i am MUCH better. I can;t tolerate methyl b12 at all even 1mg gives me a horrible headache instantly as does Same(my genetics are constistent with these experiences).Dr Yasko suspects low lithium is interfering with my transport process and taking that will mean i need less b12. I am currently fighting the PCT to get help funding and i am printing out studies, compiling a file etc for them. any thoughts?
