need help remembering... why the B12?

rebecca&nathan

A while back there was a post where the answer (or suggestion) was "take B12".  I got the B12, but DH asked why I needed it and I flat out could not remember.  All I could tell them is that a few people suggested it for something I was having trouble with.

Can someone please refresh my memory?  If the B12 is in fact for memory, I need it more than I thought!

TIA
