B12 depleting other B vitamins

[qwertystar]

I’ve been having B12 injections with all cofactors, found out I’m B2 and B7 (Biotin) deficient due to regular B12 injections.

I’m having daily injections of B2 and B7.

Shall I reduce B12 injections to once a week and restart to eod once my B2 and B7 levels are stable?

My pins and needles have stopped and I have no pain but still can’t balance.
