so, to clarify..... I should up by B12 1000mg daily to 2000mg to get my level as close to 1000 as possible? i started by B50 complex today also. i bought the vits you recommended but quite honestly have a lot of anxiety to start all of them at once as i had a panic attack once after trying to take a new bunch of them years ago. absurd i know. i took my multi vitamin last evening and i swear i didn't sleep well at all, could the multi vit do that do you know? just a thought. i really should consider a leave of absence at work. this job stresses me out, even when it is a light load. im an RN and need to have a clear head. its hard with the anxiety. anyways, Mark, how much does that test cost....to have my labs checked for hormonal balance?? thanks again.
