Just curious if any of you have had low b12 levels and do you think it affected your mental health? I start b12 injections and just praying this helps with mood, irritability, and feeling low. I will be on injections for life since can not absorb it I guess. My internal med doc found this and he doesn't even know of the ptsd. I see Psychiatric doc for first time in Oct and was hoping this helps instead of needing psychotropic meds... not that they are bad just nervous even to try them!
