Annie- I am interested in your B12 deficiency? I have nerve damage and now with them findindg all my vitamins low (including b12)... they think that might be the main issue with me neurologically (so we have to fix my stomach and hoepfully will then fix the absorption)... Did you do injections? I'm doing subliggual methylcolbalmin right now... they are setting up the injections - hopefully soon! But this has been going on for 3 years, so I"m afraid a lot of damage is permanent
