We've had some people who've had gastric surgery who daily took 3000-5000mcg of B12 so that they could count on absorbing 30mcg or each day and help rebuild stores and have enough for some repair processes (the "normal" daily requirement is somewhere around 2-8mcg).
Yes, with gastric bypass surgery you will defintiely be prone to malabsortion of many nutrients--I wouldn't be surprised if you have mineral deficiencies as well (have you been tested fo them?).

I used to take the under the tongue B12--but they were cherry flavor and made me feel so sick. I had to drink a ton of barium when I was little for a test I had, and they mixed cherry koolaid in the barium to make it taste better. All it did is make me sick every time I eat something cherry--so I need to try to find another type of B12 that doesn't involve cherry. I don't think I was on that high of a dose, though. I believe they were only 500 and I was taking two a day. I could be wrong, though.
I don't know if I have been tested for mineral deficiencies--is that also done through blood work? I had 19 viles of blood taken when I was at Mayo Clinic... they tested for everything under the sun... but that would be the only time I was tested--if I was at all.
