Do you need B-12??
I don't know how many boxes are in a case, but for whatever it's worth, I take my b-12 every day (like the box says), not just once a week like the say at Capitol. It's cheap, it doesn't hurt you, and I think it is a boost of energy. I personally think once a week is not near enough for b-12. A lot of WLS people end up with b-12 shots every month, so I figure taking the sublingual b-12 is just my insurance policy against having to do that.
You may go through the b-12 quicker than you thought.
