So does that mean a good plan would be to get it up to 5mg, take that for a couple of months (a bottle of 60 tablets), and then see how I feel dropping it back down to 1mg or 2mg? As far as I can tell, other schools of thought with regard to B12 for ME/CFS range from 1-2mg per day to much larger doses using multiple sources of B12.

Do you have any opinions on methylcobalamin vs. dibencozide, by the way?
