One size definitely does not fit all. It is a very good idea to keep track and see whether there are immediate correlations to what you are doing or not doing.

It is also important to recognize that there usually is no immediate correlation with B12.

Stomach acid is soooo important, for many things more than B12, calcium and iron absorption. Betaine hcl would be a good idea for many here. The standard method of use is to begin with one capsule with a meal, and increase the dose one at a time, backing off one when there is a warm sensation in the stomach in response. And, of course, there is a maximum dose, which may appear on the bottle.
