People who have in general a very low blood pressure -and especially when they suffer from -dizziness when getting up in the morning or in general form sitting position may be lacking vitamin B12. [nobody should jump up from his bed like a lion when waking up……that is not what the Shulchan Aruch means to say]

In case you have these problems you may want to try to suck once a week a tablet b12 [buy only METHYLcobalmine] 1000 mcg [in Israel from Solgar], you may take this for a long time and let me know if this is useful.
