It's not the fact that she needs to fix the B12 levels which bothers me.  That's typically a no-brainer and no doubt is required to be part of the treatment and aftercare of this sort of surgery.  However! It's more so the fact that rather than engaging in a conversation with me about things she could try, she was like 'yep getting a shot' as though that is going to fix all her problems. Lol.  That's very much how it came off.  But you are absolutely correct that B12 as well as other things are all needed to keep the body running efficiently! :D
