High B12 levels aren't unusual or dangerous since excess B goes right through us. Last time I had labs I was over 1500, where I have been pretty consistently all along, so keep doing what you are doing.
Keep a copy of your labs so that next time you have something to compare with and you can see if any of your levels start to trend downwards and adjust accordingly. That way you can head off any deficiencies before they become a problem.

I just got my 1 year labs done as well. My B12 was at 1999 but everything else was right where it needed to be. That's interesting that you get tingly in your foot when you reduce your intake. My doc told me to go to taking my B12 every other day so I'll see how this goes.
You'll have no problem with those last 4 lbs!
