	Re: vitamin B12 deficiency
		If your B12 is in the normal range, then getting B12 supplements is unnecessary and will not be helpful to you in any way, except possibly for placebo value (used for this purpose at times by some GP's for decades).
		If indeed you prove to be deficient, this is easily treated either with regular injections (which you can give yourself, have a friend give, or get at the doctor's office), or there alternately is a nasal gel preparation (which I use and much prefer to injections).
		In my own situation, I've monitored my B12 blood levels, and found that using this gel once every 6 weeks is sufficient.
