Thank you. I'm going back in 10 days so I will ask him about potassium. To be honest I can't remember if it was already tested and if so what level it was at.

Because of my Pernicious Anemia, do I have to worry about potassium not being absorbed as well, or is that only for B-12?

How long would it take to replenish my B12 to adequate levels? I know it's all variable and guesswork but I mean is it closer to 2 days, 2 weeks, 2 years?

I will keep taking the B12 in high doses because I can feel it working but I'm just curious how long it could potentially take.
