As Lao Tzu suggested, it would be a good idea to get your B12 levels checked. I did some searching, and it looks like high supplement intake can be a problem if you have B12 deficiency. See here:

A more accessible article here (scroll down to safety):

The recommended upper limit for supplements is 1000 mcg, but it's seems possible that you could need more, based on your individual chemistry. Definitely check to make sure you don't have a B12 deficiency, though, since it sounds like symptoms are similar for both. It's a simple blood test.
By the way, I'm not an expert about this at all. I just wanted you to be aware that there could be safety issues at that level, according to the sources I checked. Good luck!
