I definitely do. I take a multivitamin that has 200% the daily recommended value of B12 and also take an additional B12 supplement. I don't just rely on the B12 shot.

Everyone that I've seen on here has said they have small fiber PN.. you're the first to say they have large fiber PN. As I said in my original post, I also am having a hard time finding any good websites about large fiber PN. I have all the symptoms of small fiber PN, so I'm not sure why my doctor says I have large fiber PN... but then again, since I can't find out in simple terms what it is and what the differences are, who knows. I just want to find out in simple terms what the differences are in terms of symptoms and such.
