I know lots of PN'ers take B12 supplements, I take no supplements as my only "food" is Ensure supplement and the docs dont want me taking anything else (right now only one or two cans a day) and bullion broth (no nutritional value, just for salt (due to autonomic neruopathy I cant eat regular food at all).... I have been recently in the hospital a couple of times, and also am facing major back surgery that they say will lay me up at least six weeks.... I'm very worried about nutrition going in to surgery since I already cant eat, but maybe they can temporarily put in a tube....

But, they did my vitamin levels in the hospital and my B12 is 1,500.... how is that possible if I'm taking no supplements at all? Anyone have an idea how it could get so high (used to be about 750 - 800)? and if there are any ill affects? I had mal-nutrition most of the spring again due to autonomic problems, but no supplements at any time....
